What changed in EDuke32, build by build

Amend r6150.

Changes to build as C++: Apparently an extern declaration must be present for the compiler to expose the symbols of struct objects.

Changes to build as C++: pointer casting

Changes to build as C++: Structs within other structs cannot be referred to by just the innermost name, and the using keyword does not work either. Split them out into the top level.

Changes to build (in C mode).

Remove the register keyword, since it is deprecated in C++11 and removed in C++17.

Improve what build information we print to the log at startup. New feature: compilers, their versions, and big-endianness. Removed: C++, as it is now mandatory.

Visual Studio apparently still defines __cplusplus as 199711.

Address some longstanding warnings with printf when building with MinGW's GCC 6 and newer.

Introducing buildprint, a type-safe and more performant replacement for printf using C++11 variadic templates. At least, an incomplete version that is enough to implement the next commit.

Amend r6126, which doesn't leave "eduke32" defined anywhere for binary names when APPBASENAME is not specified.

Amend r6122, as of r6074 all standard library header inclusion is routed through compat.h.

Flip the switch to C++11.

compat.h: Add logbase<size_t>().

compat.h: Add new types, native_t and unative_t, functionally equivalent to our current bssize_t and bsize_t, respectively, but generated dependably using template metaprogramming when building with C++ >= 11.

compat.h: Add some infrastructure for C++ template metaprogramming.

compat.h: Upgrade our byteswapping functions with new versions that I have experimentally confirmed to compile down to the appropriate single assembly instructions on x86 and x86_64. As part of this, make them constexpr, and remove the OS-specific and inline assembly variants as sub-par due to these two improvements.

Add registry detection of the Steam path for World Tour installs.

Add the patched World Tour GRP to our checksum entries.

Modify Windows registry reading to check both 32-bit and 64-bit key locations.

Replace "gnu" with "c" in language standard declarations if we are using clang.

Address deprecation warnings with the latest Xcode and macOS.

Use -std=c99 and -std=c++03 instead of -std=gnu99 and -std=gnu++03.

Use "clang++" for building C++ with clang.

Add CROSS_SUFFIX option, as requested by rhoenie.

Move CUSTOMOPT to follow COMPILERFLAGS and LINKERFLAGS, so that it can overwrite more.

Move "-Wimplicit -Werror-implicit-function-declaration" from CONLYFLAGS to a new CONLYWARNS.

Factor out code for launching EVENT_GAME and EVENT_PREGAME.

Re-add a fixed version of old code for the SDL driver to initialize SDL as a whole or its audio subsystem if it has not yet been initialized.

Remove XYZ.voc --> XYZ.flac format upgrades completely for sound effects, and leave them only for music.

compat.h: Upgrade ARRAY_SIZE.

compat.h: Upgrade EDUKE32_FUNCTION and add EDUKE32_PRETTY_FUNCTION.

Remove the implicit "static" from our FORCE_INLINE macro.

Eliminate more cases of duplication of compat.h's functionality.

Explicitly specify the version of the C++ standard as which we are compiling.

Eliminate many cases of duplication of compat.h's functionality.

Define NOMINMAX in windows_inc.h.

Route inclusion of all Windows headers through a new header, windows_inc.h.

More of the previous commit, because VS can be frustrating.

Try fixing synthesis.sh.

Some tweaks to the cleanup.

I hoped ./ prefixes would work in a ignore on Windows.

Bring the previous commit into effect.

The great repository rearrangement of 2017.

Delete the default suffixes, to possible help avoid internal Make race conditions.

Only pass APPNAME and APPBASENAME to the preprocessor if a value for them was passed in.

Fix audiolib bindings, again.

Fix some vec2_t stuff I missed.

"new" --> "New"

Bump LuaJIT to git HEAD >= 2.0.4. BUILD_LUNATIC.

Update libvpx to 1.6.0.

We have not needed to disable the stack protector when building Windows libs for a while.

Replace wiibuild.bat with wiibuild.sh.

Uncomment copytilepiece(). KenBuild uses it.

Fix the interaction between the definitions of the NEW_MAP_FORMAT structs and the structure trackers.

buildtypes.h: Replace the *TYPE macros with a StructName concatenation function.

Add extern "C" to screentext.h so that Lunatic can see its symbols when building as C++.

Fix build, part 13. Disable inaccurate assertion.

Fix build, part 12. playerswhenstarted --> g_mostConcurrentPlayers

Extend SE 26 to use the value provided by a GPSPEED, if any.

Remove bounds check on rotatesprite coordinates.

Perform keyboard layout switching whenever window focus is gained or lost.

Make layout switch duplicate guard bidirectional.

Refactor keyboard layout switching code into winbits.c and clean it up. No functional changes.

Fix linking of mdpause variable with POLYMER=0 in screens.c, exposed by Visual Studio. DONT_BUILD.

Fix STARTUP_WINDOW=0 on Windows so that the resource objects are built, but the editor's startup window is not. DONT_BUILD.

Extend STARTUP_WINDOW to GTK. DONT_BUILD.

Fold OSX_STARTUPWINDOW into STARTUP_WINDOW. DONT_BUILD.

Avoid unused variable warning with the startup window disabled. DONT_BUILD.

Add support for MOD, XM, IT, and S3M tracker music through libxmp-lite.

Remove disabling certain mouse features under debug builds. It makes mouse aiming unusable.

Remove -fno-pic from everywhere. This should fix building on Ubuntu 16.10 and any other platform that has PIE enabled.

Revert r5864 and move some code introduced in r5762 to a later Mac-only block so that architecture detection is not broken on Linux.

Work around warning: signed and unsigned type in conditional expression [-Wsign-compare] indirectly caused by the SDL 2.0.5 headers making all preprocessor macro literals unsigned.

Add #ifdef USE_OPENGL forgotten in r5024 that causes an OOB access in scansector() and glitchy mirrors with USE_OPENGL=0.

Amend r5911 to use undefinetile instead of only zeroing out the MIRROR tile's dimensions.

Extend undefinetile to also remove voxels, hightile (including skyboxes) and models.

Add vox_undefine().

Amend r5910 so that the problem is mitigated even when the map load takes place with a different renderer.

Revert a formatting change from r5725.

Move the nulling of the MIRROR tile to after defs are parsed so that tilefromtexture does not interfere with mirror function.

Clear wsprinfo[] upon map load. This should address some remaining instances of wall-ornamented sprite z-fighting.

To avoid potential compiler bugs when inlining inline assembly, remove the asm variants of msqrtasm and always use the C version. Compilers generate equivalent or better assembly, and the function is used exactly once, in a routine called during startup.

C-CON and M32script: Only accept hex literals beginning with '0' and not any other digit.

Fix the parser so tokens with 'x' or 'X' as a second character are only treated as hex constants when the first character is '0'. Introduced in r5822.

Fix the off-by-one error when printing line numbers.
