I have managed to get a relatively successful build:

So the failure is that putenv test where there seems to be no way 
to remove an environment variable using C under Solaris.  Which 
seems bizarre.  I have looked through `man -s 3 intro` and can see
the putenv() & getenv() functions, but nothing to remove an environment
variable.

We are not the only ones banging into this problem:

http://gollem.science.uva.nl/SWI-Prolog/mailinglist/archive/2006/q1/0155.html

makes pretty disturbing reading.  Given this a basic requirement of
shells, I don't understand this lack of an unsetenv() function.

And there's this:

http://www.gnu.org/software/autoconf/manual/html_node/Function-Portability.html

which doesn't really give a solution either.

Despite:

I find

How did I get to a relatively successful build?

Well, I applied the patches:

Which I built after all the hassles with gcc-4.

And I used --disable-error-on-warning

OK, so what about gcc-4?

gcc (GCC) 4.1.0

gives me, using the same build script:

rm -f .libs/guileS.c .libs/guile.nm .libs/guile.nmS .libs/guile.nmT

I'm not sure what to make of this difference in behaviour.

So, is there anything else you would find it helpful to know?
And have you any advice about my GCC-4.1.0 (which would be off-topic,
but you can just say "no". :-))
