Most of them are already aligned to their natural boundaries, so lowering
the alignment to 1 byte can only worsen things by making the C compiler
generate poorer (unaligned access) code for some platforms.
The layout of structures is not specified by the C Standard, but is rather
given by a particular platform + toolchain's ABI (application binary interface).
Most ABIs follow the expected pattern "alignment of scalars is their size,
alignment of arrays is that of its element type, alignment of structs is the
maximum alignment of its members". A couple of links to particular ABIs are
given in build.h.
Problems are expected with archs that care about unaligned access when a pointer
to a non-packed struct is taken that resides in a packed aggregate, but these
uses should be weeded out (I'm not sure if there are any in our codebase).
The following types are affected, only hitdata_t changes its size:
sectortype, walltype, spritetype, spriteext_t, spritesmooth_t,
struct validmode_t, picanm_t, palette_t, vec2_t, vec3_t, hitdata_t.

If enabled, dragging wall vertices will correct the xrepeat after the
mouse button is released, so that the pre-drag absolute stretching is
restored.

Also, add another flag, signifying that from the editor, also the
"lastwall"s (i.e. the CCW-linked points) should get collected. This is
to signal the editor that their wall lengths should be displayed, too.

- Stop using memcache on some other failure paths, particularly when
failing to read from the on-disk texcache.
- Factor out cache reading code (3x).
- Fix endianness issues affecting big-enadian systems (one introduced by
r3382, one existing before). Comment each B_LITTLE32 with whether we're
converting from native to on-disk (little) endianness or back.

The SDL and Windows layers had slightly different code: the latter would
dereference a NULL pointer if stdout.txt failed being write-opened.

Preventing a continuously growing stack top and inevitable program termination.
Also, commonize the error handling to live on the engine side.

- Rewrite the "clear background" routine in a no-brainer way instead of
juggling around with rotatesprite(). Make it common to game+editor.
Expose glRectd to glbuild.
- Don't stop OSD text line drawing when encountering a non-printable char.
Instead, treat it as space.
- In OSD_SetTextMode(), don't use swaplong (which really swaps 32-bit ints)
to swap pointers. Write an analogous "swapptr" instead.
- When changing from/to OSD, don't inject a pause key. This *might* have been
the cause of the reported pausing problems.
- clean up the code...

Implemented using GL_LINEAR fog. The only source of difference (besides the
obvious indexed vs. true color) should now be the distance constant, which
still had to be determined experimentally. Polymer implements this mode in
its fog fragment program part.
Parallaxed skies are always drawn with full visibility, I'm not sure if there
are any maps that expect otherwise.
Also, accidentally committed: factor out initialization code from
polymost_printext256() into gen_font_glyph_tex(), small game.c changes.

It was caused by the definition of c_dfDIJoystick using literal 24 and 16 values in place of sizeof(DIDATAFORMAT) and sizeof(DIOBJECTDATAFORMAT), which include pointers. On 64-bit, the values end up being 32 and 24, causing a discrepancy in which DIERR_INVALIDPARAM was thrown.

This global option will set bit 1024 and clear bits 256 and 512 for all
rotatesprite calls, fixing complex HUD drawing code relying on precise
alignment of individual elements (widescreen rotatesprite is entirely
unsuitable for this purpose).

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.

The two uses are from hitscan and neartag. The functionality is reproduced
exactly (assuming I made no mistake), down to different distance checking
(<= vs. <).

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.

This needs improvements to bring it up to par with winlayer, but it is functional. In particular, a good amount of code from winlayer could be used for both layers, including the profiling timers, the version printing code, and the hInstance and hModule sharing.
Known problems: the mouse cursor is not trapped, and the game starts before the startup window shows options.

and the z offset is returned instead of set by pointer.
