- wrapper for atan2 that deals directly with special cases before
- delegating to the platform libm for the remaining cases. This
- is necessary to get consistent behaviour across platforms.
- Windows, FreeBSD and alpha Tru64 are amongst platforms that don't
- always follow C99. Windows screws up atan2 for inf and nan, and
- alpha Tru64 5.1 doesn't follow C99 for atan2(0., 0.).
