Hi,

I am currently reinstalling OS X and I am not quite done.  So there may
be some delay for the test but I will try to do it today.

The -lc_r instead of -lpthread is on FreeBSD and not Darwin.
Darwin dit not like the -lrt.  I will do some tests and fix it.
Darwin has a single libSystem and all libc, libm etc. are only
symlinks to libSystem.  So all libs works on Darwin except -lrt as it
does not exist and there is no librt symlink to libSystem.
