What changed in EDuke32, build by build

This includes a complete Windows header and library refresh, including the addition of 64-bit compiled libs: *libogg 1.3.0 *libvorbis 1.3.3 *zlib 1.2.7 *libpng 1.5.13 *libvpx 9a3de881c0e681ba1a79a166a86308bbc84b4acd *SDL_mixer 1.2.12 (for RENDERTYPE=SDL) *DirectX import libraries: dsound and dxguid (now included) To build in 64-bit, you essentially need MinGW's MSYS (but not MinGW itself) and MinGW-w64 at the top of your PATH. The target is automatically detected using `$(CC) -dumpmachine`. The EDukeWiki will get detailed instrucitons. All compiler and linker warnings when building in 64-bit mode have been fixed. Remaining 64-bit to-do: - The ebacktrace dll does not build under 64-bit. It uses code specific to the format of 32-bit executables and will have to be ported to work with 64-bit executables. A future 64-bit version will be named ebacktrace1-64.dll. - RENDERTYPE=SDL crashes in SDL_mixer's Mix_Linked_Version(). - DirectInput gives an error and does not function. This only affects joysticks, and the error never happens without any plugged in. - Port the classic renderer ASM to 64-bit. (Just kidding, this is way out of my league.) This commit includes a fair bit of Makefile development spanning all platforms, including simplifying the SDLCONFIG code, fixing build on Mac OS X (thanks rhoenie!), globally factoring Apple brew/port inclusion, enforcing that all -L come before all -l, and ensuring that $(shell ) is always :='d. In addition, I have resurrected the old GCC_MAJOR and GCC_MINOR detection using `$(CC) -dumpversion`, but I have made it failsafe in case the command fails or the version is manually specified. I have applied this new fine-grained detection where applicable, including allowing LTO, and restraining -W's to versions that support them.

Also, fix deficient logic in Gv_Free and Gv_Clear (both M32 and CON) so that gamevar and gamearray erasure results are (closer to) correct, and so that the game does not crash when system arrays are accessed from CON because they all have been nulled.

This introduces winbits.[ch] in the engine, containing layer-independent code migrated from winlayer, including nedmalloc, ebacktrace1, OS version detection, and high-resolution profiling timers. sdlayer has been expanded to include the code from winbits under _WIN32. All uses of RENDERTYPEWIN in the source have been examined and changed to _WIN32 (or removed) where the block in question is layer-independent.

- Eliminate use of the C++ standard library from arttool. I improved some of the program's workings but it continues to corrupt my art files in certain circumstances. (Note: Not a regression; it happens with previous revisions.) - Construct "make utils" for the game side following the pattern of the engine. - Move ivfrate to this new distinction. - Minor Makefile cleanup and tweaks, mainly to facilitate CLANG=1 and to formalize text output in special cases.

Credit to Plagman for the idea and doing the work on the game side, which is included in this commit. (Building as C++ will give us features with which we can make improvements and optimizations on the multiplayer code and Polymer.)

These control the maximum difference in height between two sectors that the player will automatically traverse without needing to jump. The latter controls the special case when the player's sector's lotag is ST_1_ABOVE_WATER or p->spritebridge == 1. BYTEVERSION bumped.

* Centralize optimization strategies in Makefile.common. This required moving detection of $(PLATFORM), which makes sense if we work on the paradigm that Makefile.common is for generic compiler setup and Makefile.shared works with libraries and things closer to the engine and game code itself. * New Makefile variables OPTOPT (Optimization Options) and CUSTOMOPT (Custom Optimizations). OPTOPT by default contains -march, -mtune, etc. Setting this variable from Make invocation will blank these. CUSTOMOPT (Custom Optimizations) works the same but in an additive fashion, overwriting nothing. Technically CUSTOMOPT could stand for (Custom Options) and include any additional parameters sent to both linker and compiler. * Factor out literal names of the main executables. * The build process now prints assembler (if NOASM=0) and linker settings in addition to compiler settings.

1. EVENT_PREGAME 2. hardcoded stuff 3. EVENT_GAME One potential use is to examine values which are clobbered by commands such as ifhitweapon/ifwasweapon.

NAM and Napalm can now share their con, def, and rts files if the one for their respective game is not present because the con and rts files are identical. Also, decapitalize two string literals missed in r2540.

Note: You may encounter a crash if you try to test your map and Mapster32 is running fullscreen.

- Fix typo, correctly adding SDL libs to the tools on OS X so that makesdlkeytrans builds. - Move all mention of $(LIBS) out of build/Makefile into build/Makefile.shared because no linking takes place in the engine itself so LIBS additions were lost. This should fix USE_LIBPNG=1 on Windows at least. - Other assorted cleanup.

Also, a very minor change in the con/def module code. (int --> int32_t)

The main feature is the addition of -mx and -mh command-line parameters to EDuke32 and Mapster32. These parameters include a con and def "module" respectively. This translates into essentially including the file from the bottom of the compiled script. I fixed the classic buggy behavior of the BROKEHYDROPLANT and REACTOR2 sprites. I also fixed a small, long-standing bug where FRAMEEFFECT1 blurs are not affected by sector floorpal. You can see one example of this by shrinking the Enforcer on the upper inside of the toppled building in E3L11: Freeway. I tweaked the Makefile so that it would automatically regenerate the keep.me files in the $(OBJ) and $(EOBJ) directories after they are deleted for cleaning. One final change is a slight positioning cleanup of both programs' --help dialog boxes.
