<limits.h> used to be a header file with no declarations. GCC's libgomp includes it in a #pragma GCC visibility hidden block. Including <unistd.h> from <limits.h> (indirectly) declares everything in <unistd.h> with hidden visibility, resulting in linker failures. This commit avoids C declarations in assembler mode and only declares __sysconf in <limits.h> (and not the entire contents of <unistd.h>). The __sysconf symbol is already part of the ABI. PTHREAD_STACK_MIN is no longer defined for __USE_DYNAMIC_STACK_SIZE && __ASSEMBLER__ because there is no possible definition. Additionally, PTHREAD_STACK_MIN is now defined by <pthread.h> for __USE_MISC because this is what developers expect based on the macro name. It also helps to avoid libgomp linker failures in GCC because libgomp includes <pthread.h> before its visibility hacks. Reviewed-by: Carlos O'Donell <carlos@redhat.com>
