We rely on proper IEEE 754 behavior in too many places for this.
See also commit 2fdbbeca43 with equivalent
change for autoconf.

Haiku targets the Pentium or higher processor.
To ensure compatibility we can do march 586 and
mtune 686. Mesa will still use sse however if
the cpu supports it (and the stack is properly
aligned). These flags only effect the internal
compiler optimizations.
The warning is absolutely useless. It doesn't actually say that there are
uninitialized variables. It points out the fact that there are missing
initializers and that variables are initialized to zero implicitly, which is
exactly what we want and what we commonly make use of.
C90 and C99 require all unspecified variables in the initializer list to be set
to zero.
-g3 causes binaries to be 3x - 10x bigger, not only on MinGW w/ dwarf
debugging info, but linux as well.
Stick with -g, (which defaults to -g2), like autoconf does.
Optional parallel rendering of spans using OpenMP.
Initial implementation for aa triangles. A new option for scons is
also provided to activate the openmp support (off by default).

platform.system in SCons on Cygwin includes the OS version number.
Windows XP - CYGWIN_NT-5.1
Windows Vista - CYGWIN_NT-6.0
Windows 7 - CYGWIN_NT-6.1
Reduce all Cygwin platform variants to just 'cygwin' so anything
downstream can simply use 'cygwin' instead of the different full
platform names.
Use scons target and dependency system instead of ad-hoc options.
Now is simply a matter of naming what to build. For example:
scons libgl-xlib
scons libgl-gdi
scons graw-progs
scons llvmpipe
and so on. And there is also the possibility of scepcified subdirs, e.g.
scons src/gallium/drivers
If nothing is specified then everything will be build.
There might be some rough corners over the next days. Please bare with me.
The Mac OS X SCons build failed on 32-bit CPUs starting with commit
2f6d47a7c8 during linking of graw-null.
The build succeeds though on a 64-bit CPU. See FDO bug 29117.
This was the compiler error.

The patch adds -fno-common to all Mac OS X builds to work around this issue.
Now that draw depends on llvm it is very difficult to correctly handle
broken llvm installations. Either the user requests LLVM and it needs to
supply a working installation. Or it doesn't, and it gets no LLVM
accelerate pipe drivers.
