Here is qbsp, vis and light for Solaris 2.4, SCO3.2v5.0.0 and Linux-ELF.

The Linux version doesn't have thread support.  Haven't played with Linux
pthreads yet.  The linux gcc options were:
-O6 -funroll-loops -ffast-math 

The Solaris version fully support Solaris bound threads.
They use fast math and SuperSparc instructions.  They will NOT run on 
MicroSparc (Sparc5) machines.  Only SuperSparc ones (Sparc10, Sparc20 and 
beyond).
Got a multiprocesssor Solaris box?  Go for it!  Default thread count is four.
The Solaris compile options were:
-O6 -funroll-loops -ffast-math -msupersparc 

The SCO version also doesn't have thread support (does SCO have thread
libraries?).  The compile options were:
-O

qbsp:  This is version 29/31 from Carmack.  I have fixed the bug where a
.pts file was *not* generated on a leak.  Works great.

light:  Solaris thread support added.  No progress indicator, but light
doesn't take hours to run like vis.  :)

vis:  This has been modified to include a precentage done indicator.  Just
use -show on the command line.  I use:
	vis -threads 2 -show mylevel.bsp

I did this 'cause I needed 'em.  Unsupported.  Most email about 'em
will get deleted.  Sorry.  I'm busy enough with the ThreeWave CTF stuff
as it is!
