Using a pre-release snapshot of gcc-2.3, I was able to compile all of
IV-3.1beta2 on a DECstation-5000/120 running Ultrix 4.2.

I made the following changes:

in src/bin/dclock/clocktime.c, I added 'ultrix' to the #ifdef list in
``void Clock::GetTime''

I added the following to my local.def:

#define TIFFStdCDefines \
    -DCOLORIMETRY_SUPPORT -DYCBCR_SUPPORT \
    -DHAVE_IEEEFP=1 -DUSE_VARARGS=0 -DUSE_PROTOTYPES=1
	
	I think gcc.def should probably override the TIFF.def
	defaults - gcc provides stdargs, and IV should use it.


Idraw, iclass and ibuild appear to work (didn't play with ibuild much)
-- however, the 'doc' program still dies on startup

Thus, when gcc-2.3 is released (sometime in october, I think) it looks
likely that it will compile interviews out of the box.
