[cfe-commits] [libcxx] r144501 - /libcxx/trunk/include/__config

[David Chisnall]

Author: theraven
Date: Sun Nov 13 11:15:33 2011
New Revision: 144501

URL: http://llvm.org/viewvc/llvm-project?rev=144501&view=rev
Log:
On FreeBSD, define a macro that causes the unimplemented C99 math.h functions to be declared.  This prevents <cmath> users from being broken, unless they actually use the C++ wrappers that call the missing functions.
