I spent a bit more time on this, but I have to quit now.

The problem here is that if <math.h> is included with _POSIX_C_SOURCE  
defined, the gamma(), rinttol() and roundtol() functions among others  
are not declared.  wx/mac/private.h, which is included from  
helpers.cpp, includes <Carbon/carbon.h> .  The carbon header  
eventually includes fp.h.  The #ifdef on line 124 of fp.h prevents  
the declarations of gamma() etc being used from fp.h.  Hence the errors:

This leaves me with questions:
Is the Carbon framework POSIX C compliant?
I suspect that it is not.  So how and where should _POSIX_C_SOURCE be  
undefined?
If _POSIX_C_SOURCE is undefed does that bring back the strcasecmp issue?
