Replace finite function with C++ <limits> features

[mloskot]

In HTCoordinate.cpp:197​ file finite function is used. The finite() function is obsolete also in POSIX and replaced with isfinite macro. Unfortunately, isfinite() was added in C99, so it's not available in ISO C++/2003.

Here is proposed solution that conforms to C++ standard, replace line 197:

f ( ! finite(static_cast<double>(a)) )

with following:

// Put this next to existing #include directives
#include <cmath>
#include <limits>

// replace line 197 with this line
if (std::fabs(a) > std::numeric_limits<double>::max())

Originally reported as ​OSX 10.5 compile problem by William Kyngesburye

That did it. Note, there are two places where finite() is used, line 197 (getX()) and line 211 (getY()).

I've just applied this fix to trunk (r2043)
