Janis, THANKS! Using either... make -k check RUNTESTFLAGS="--target_board=unix'{-m32,}'"
or make -k check RUNTESTFLAGS="--target_board=unix'{-m32,-m64}'" ..works from the toplevel directory (at least for x86_64 on Fedora Core 5...I'll try darwin when I get home to my G5). Jack ps I don't see anything in gcc/gcc/doc when I grep... grep make * | grep check | grep target ...that covers running both 32-bit and 64-bit tests on multilib systems. With the rise of 64-bit platforms, it might be good to add a blurb somewhere in the docs.
