Over the weekend, I successfully tested a different way to configure and build: all static libraries. If you build and privately install GMP, MPFR, MPC and LIBICONV configured as static libraries (--enable-static --disable-shared) and install in /prereq, then, combined with your patch to enable --static-libstdc++ --static-libgcc, the resulting GCC only depends on AIX libc.a -- no other shared libraries. Bull Freeware can distribute the shared versions of the libraries for other applications, but they do not need to be GCC dependencies. - David
