Author: dim Date: Sat Nov 10 21:22:10 2012 New Revision: 242879 URL: http://svnweb.freebsd.org/changeset/base/242879 Log: Only define isnan, isnanf, __isnan and __isnanf in libc.so, not in libc.a and libc_p.a. In addition, define isnan in libm.a and libm_p.a, but not in libm.so. This makes it possible to statically link executables using both isnan and isnanf with libc and libm.
