That's about undefining it. I suggested keeping it defined, but changing the definition from empty to "". You should, however, examine the code paths used in libgcc to convince yourself that __LIBGCC_INIT_SECTION_ASM_OP__ does not actually get used as an asm argument on Darwin (either directly or via CRT_CALL_STATIC_FUNCTION) - though if it did get used, I'd have expected you to have got syntax errors from asm () before my patch. (As far as I know, asm () is not valid syntax anywhere.)
