Hardware:	Olivetti CP486
OS:		SCO Unix V3.2
g++:		1.37.2	(i386-sysv)
libg++:		1.37.2
gcc:		1.37.1	(i386-sysv and i386-sysv-gas (see below))

I have currently got gcc compiled and running beautifully (it's not using gas
at the moment).  G++ compiles ok, as does libg++, assuming I tell it to use
COFF type stuff.  Unfortunately, when I try to compile something else (it was
groff, actually) I get problems with multiply defined symbols.  These occurs
when there are two static members of different classes with the same name.
I seem to remember I had some other problems with this system, but they
temporarily escape me.

I thought it might be a assembler/linker problem, as groff has definitely
been compiled with g++ (on a Sun, I believe), so I switched to plan B.
I compiled GNU-ld and gas (1.35) and also recompiled gcc to use these with
COFF encapsulation.  At this stage I couldn't convert libc.a to the BSD
type format used by GNU-ld as the conversion program doesn't cope with
multiple data segments in object files.  I tried to modify robotussin (the
conversion program) but then I started getting multiply defined symbols in
libc.a (as opposed to undefined ones from before).

At this stage I have more or less given up, but I would really like to compile
groff.

If anyone has got g++ working _well_ under SCO, could then drop me some mail
and tell me what they did.  Please be as specific as you can.

Thanks in advance.

Mykel.
