I agree, how about this patch? Can we at least get this into the Makefile
so it makes the 'release' builds work on Sparc until we can fix the
problems and use heavier optimizations?

Yes, I ran it and with the optimized version and purify, I got a lot more
UMR's (Uninitialized Memory Read) than with the debug version.
I ran it with:
releasesparc/SunOSquake3 +set vm_game 1 +set vm_cgame 1 +set vm_ui 1 +set sv_pure 1 +set ttycon 0 +map q3dm17
It died inside the botlib initialization. Purify shows 'MAW' (Misaligned
Memory Write) just before the crash. I got the following trace but I
cannot make anything of it:
MAW: Misaligned memory write
This is occurring while in:

+Compiling and Running under Solaris/x86 or Solaris/Sparc
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Follow the Linux instructions on installing, that should get you started.
+
+ioQ3 was tested on the the following systems:
+- Solaris Express on x86 using Software OpenGL.
+- Solaris 10/Sparc GA on a SunBlade 2000 with XVR-1000 graphics.
+- Solaris 9/U8 on a SunBlade 150 with XVR-600 graphics.
+
+The dedicated server and client work on x86.
+The dedicated server and client work on sparc
+
+Don't use anyting other than -O0 on sparc, otherwise it will crash due to alignment errors.
+We're investigating this issue (Nov 10th 2005).
+
+The executables survive some less global optimization flags. So we're getting
+this ugly 'OPTIMIZE' for the release build until we get the other stuff fixed..
+Verified 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)
