Yeah, in theory that would be nice, but so far not having any luck with it. Two of the three dependent libraries will only work as 64-bit on Solaris / SPARC, and gcc will only by default compile as 32-bit, so it's a no-go. As it stands, looks like I have two choices: A. Communicate with the mpfr and mpc folks to see if there's any way to get these to compile successfully in 32-bit mode. (Which I can do with gmp!) B. Figure out how to alter the specs behavior of the gcc during the build process to default to 64-bit so that the xgcc stages will not continue to insist to build 32-bit (despite what the env vars have specified.)
