I lied before [0] and I do see this. Why are we using 'LD_LIBRARY_PATH' instead of --disable-libgomp in pass2 as we do in pass 1? (yes, I'm well aware that it was me that committed r9254 that added this as part of the upgrade to GCC-4.5.0). If noone has any objections, I'll change this to what we do in pass1 once I've tested it does the right thing. Regards, Matt.
