gcc-3.1 + libstdc++-v3.0.97 cross compile ok?

Subject: gcc-3.1 + libstdc++-v3.0.97 cross compile ok?
Should I be able to cross-compile (i386-sun-solaris2.6 to
sparc64-sun-solaris2.8) with gcc-3.1 and libstdc++-v3.0.97?  I've been
working with the compiler folks on some 64-bit bugs, and once all that
was ironed out, I tried to set up the compiler on my (fast) build
machine.  I ran into some snags where it _looks_ like
libstdc++-v3.0.97 was picking up host features and putting them in
c++config.h as if they were valid for the target.

Before I look any further, is this a known issue?  BTW, I did get it
to work simply by editing c++config.h by hand.

Example errors, for the record:

/bin/sh ../libtool --tag CXX --mode=compile
