Hi Iain, We don't want to run dsymutil if there are .o files, let the developer do that. If someone just does gcc -g -o foo foo.c, then any debugging information will be lost when the temporary .o file is removed, thus, to allow debugging such a foo, the compiler must run dsymutil. Of course, it doesn't need to run for stabs, or -g0. Strange, Apple's gcc-4.2 doesn't have this bug (-lm), yet that portion of the specs appears identical. Peter
