[quake3] Re: Quake3 client + server on Solaris/Sparc

[vincent at cojot.name]

Tim, Ludwig,

Could you please commit the following workaround?

It makes the 'release' version work on Solaris/Sparc (s9 and s10) by 
working around some of the optimizations that make the executables 
segfault.

It's ugly but at least it will make both the debug and release versions 
work out of the box for people who compile from source.

Tested on:
   # SunOS 5.9 Generic_118558-14 sun4u SUNW,Sun-Blade-100 / gcc3 (GCC) 3.3.5
   # SunOS 5.10 Generic_118822-11 sun4u SUNW,Ultra-5_10 / gcc (GCC) 3.4.3 (csl-sol210-3_4-branch+sol_rpath)
   # SunOS 5.10 Generic_118822-11 sun4u SUNW,Sun-Blade-1000 / gcc (GCC) 3.4.3 (csl-sol210-3_4-branch+sol_rpath)

Thanks,
