svn commit: r227472 - head/lib/msun/src

New Revision: 227472
URL: http://svn.freebsd.org/changeset/base/227472

Log:
  Expose the unimplemented libm functions in the math.h header.  This allows C++'s <cmath> to work without the compiler complaining that the C++ versions are calling implicitly-declared functions.  You will still get a linker error when they are called.  OpenBSD 5.0 claims to fully implement the C99 <math.h> stuff, so might be worth investigating...
