Hi,

ape/math.h defines Inf, isInf, NaN, isNaN; but I cannot find them
in either ISO C standard, or my POSIX reference. Inf results in
a name conflict with an otherwise POSIX compliant source.

Instead, ISO/IEC 9989:1999 (The ISO C Standard) defines

isinf() and  isnan() macros, which are absent from the library.
