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...
