handling SIGTTIN/OU allows running Doom3 in the background (or even
sending it to the background with Ctrl-Z + bg) by disabling TTY input
(before it would get stuck when run in background without +set in_tty 0,
see #215)
While at it, I also added signal handlers for some common crash signals
(SIGILL, SIGABRT, SIGFPE, SIGSEGV) to print a backtrace before exiting
the game (partly based on Yamagi Quake II code).
Since we don't have our own signal handler anymore, those two
init functions can be merged into the existing Sys_Init(), which
is already called by common->Init().
Split fs_savepath for config files. This is in preparation for
moving the writable paths on *nix to $XDG_DATA_HOME and
$XDG_CONFIG_HOME.
Affected files: config.spec, *.cfg, doomkey, xpkey.
SDLmain.m does the bulk of the work for us, so get rid of
the DOOMController NSObject, move the quakeMain() contents to
main() and let SDL do its thing.
Add missing SDLMain and icon/resource files to generated .xcodeproj
Now builds on Lion in XCode4 with the 10.6 SDK using LLVM-GCC4.2.
Also tested on WinXP in VS 9 2008 Professional, I don't appear to have
broken anything there, stuff like MACOSX_BUNDLE_INFO_PLIST is
effectively ignored.
Get rid of the 2 CPUID flags and combine them with SSE in one
implementation.
SSE flags can now be set on all x86 and x86_64 platforms -
independent of -ffast-math.
Helper defines borrowed from STREFLOP.
Use SDL_main on all platforms.
Fix main() for non-const argv so it matches with the SDL
prototype.
Adapt win32 WinMain() to main() and get rid of the win32 special
case in Common::Init().
Don't include the lazy precompiled.h everywhere, only what's
required for the compilation unit.
platform.h needs to be included instead to provide all essential
defines and types.
All includes use the relative path to the neo or the game
specific root.
Move all idlib related includes from idlib/Lib.h to precompiled.h.
precompiled.h still exists for the MFC stuff in tools/.
Add some missing header guards.
Thread return types are different between platforms, and its
probably not a good idea to return something of a different size,
cast the callback and expect it to not crash.
