[cp-patches] FYI: Define isnan explicitly in fdlibm

[Guilhem Lavaux]

Hi,

Here is a patch to define isnan explicitly as a macro if it is not 
already defined. At the same it removes the symbol renaming in namespace.h.

Cheers,

Guilhem.

ChangeLog:
2005-12-17  Guilhem Lavaux  <address@hidden>

        * native/fdlibm/namespace.h: Regenerated.

        * native/fdlibm/fdlibm.h
        (isnan): Define explicitly isnan if it is not a macro.

        * scripts/math_symbols: Removed isnan.
