Fix a warning with SDL_TARGET=1 builds.

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

Revert a formatting change from r5725.

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.

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.

Fix improper matching of loop tags with initial substrings of them, and add proper support for LOOP as a synonym of LOOP_START.

Fix addlogvar command, broken in r5835.

Apply the same bugfix as r4947 to XA sounds so that they only loop when intended.

Remove the Polymer aspect ratio option, as it was always broken, and I don't know what purpose it has besides configuring non-square pixel stretching, which we have a long way to go in terms of configuring anyway.

Ensure the cached float cast variables introduced in r4656 are updated any time the integer versions are.

Fix ghost tsprite bug introduced in previous commit.

Finish what r5484 started but got reverted in r5723. Cstat 1024 now works properly in Polymost without causing any side effects in Classic. It remains unimplemented in Polymer.

Reinstitute the cosmetic cleanups that should have been a separate commit from r5484 and were reverted in r5723.

Fix MIDI playback on Windows, broken in r5817.

Fix warning: left shift of negative value [-Wshift-negative-value]

Revert part of r5481. We can't rely on the sprite trackers to tell us when tsprites change.

Restore some accidentally-working cases of SEs 5, 6, 14, and 30 broken in r3161.

Revert r5658. This fixes the disappearing chaingun problem.

Fix the oversight in handling tspr->extra from r5400 by setting it to zero in polymer_scansprites.

Clean up fallback video mode attempt code in order to fix at least three bugs.

Fix build. BUILD_LUNATIC.

Output the postprocessed Lunatic symbol lists to $(DUKE3D_OBJ) so they don't need special cleanup and ignore rules. Also fix building the Lunatic-enabled editor on OS X.

Fix erroneous tab characters.

Fix OS X build.

Fix symbol issues.

Reorder preprocessor lines in libdivide.h so that LIBDIVIDE_USE_SSE2 is defined before emmintrin.h is included. Fixes ticket #23. DONT_BUILD.

This seems like a bugfix.

Fix an unused variable warning introduced in r5696.

Revert post-r5496 warning cleanup.
