as reported by Daniel Johnson: "This may be too bleeding-edge for b.g.o, so I figured I'd shoot you an email instead. As of at least a couple weeks ago, glibc won't configure against GCC from subversion. The config line that fails is when it performs roughly the following action: gcc -v --help 2>&1 | grep z relro Prior to 4.5.1-pre9999, gcc's verbose --help would include ld's verbose --help, and it's ld's help that includes the relro information. Therefore, glibc's configure script should be patched to test ld instead of gcc for relro." I haven't done any investigating yet. Daniel, did you get a chance to?
hrm, I can't reproduce this. dirtyepic@halo ~ $ gcc -v Using built-in specs.

it seems to work for me here. let me know if there's something i'm missing.
