Well, fair enough. And you're right, solaris (which is where msun came
from a long time ago) still has the _REENTRANT. I should have looked at
some of the solaris machines I have accounts on.

Does the conditional that Mike Barcroft suggested:

#if defined(__BSD_VISIBLE) || (defined(__POSIX_VISIBLE) && defined(_REENTRANT))

Seem reasonable to you?

Regards,
Ben
