I use something like
CONFIG_SHELL=/bin/ksh $srcdir/configure --with-gnu-as \
--with-as=/usr/sfw/bin/gas --enable-languages=c,c++
--with-gmp and --with-mpfr shouldn't be necessary, since both live in
/usr and should be detected automatically.
Please note that I didn't yet test on Indiana, and recent testing on
SX:CE 124 detected a couple of ld bugs that broke the libstdc++.so build.
The fixes should be integrated shortly.

Care to explain why? The 4.2.x family isn't supported by the GCC
project any longer.

As Solaris GCC maintainer, I'll oppose such a patch: it adds to the
testing matrix and complicates things needlessly. As long as any
Solaris release still supports x86, we'll have to keep the multilib
support. In fact I think the sparcv9-sun-solaris2* configuration was a
mistake, too.

To avoid problems, I've always built gmp and mpfr statically myself.
Given that they are already included in OpenSolaris, this shouldn't be
an option.

Should be relatively painless, modulo the ld bugs above.
