how to handle <cmath> and the like ?

[Laurent Duflot <duflot@xxxxxxxxxxxx>]

   Hi,

in porting to other architectures, how can I handle the use of <cmath> and the
like ? It seems that I need to use them on Linux with the KAI C++ compiler.


I propose to use 

#ifdef HAS_CSTDLIB
#include <cstdlib>
#endif

#ifdef HAS_CMATH
#include <cmath>
#endif

and the HAS_XXXX should be set by the build system. 

   Any comment ?
