A *Very* quick look following a prompt from Jack...

removing the _ext should have no effect since -lgcc, which follows it, but
precedes the -lSystem should cause the math function to be linked statically
from libgcc.a (4.5 version)
[the _ext will cause it to be linked dynamically from libgcc_s (4.5 version)]

it seems on the face of it that there's different behavior from this function
as supplied by the Darwin environment [libmath=>libSystem] and as supplied by
gcc. 

Of course, it's also possible that the code differs between the static and
dynamic builds of libgcc...
