2017-08-06Add tests for C99 math functions, hypot, atanh, cbrt, etc.Charles Karney
This tests whether the functions are declared in <math.h>. If they are, then -DHAVE_C99_MATH=1 is added to the C flags. The intention is that this flag is only seen when building proj.4 and shouldn't be referenced in any of the installed include files. The next update to geodesic.c will use this flag. Left unaddressed is what to do if HAVE_C99_MATH is 0. The strategy in geodesic.c is to assume that the missing functions will need to be defined explicitly. A less safe alternative is to assume that the functions are in fact available in libm and that all that needs to be done is to declare the functions.
