perlguts: PTR2ul() is unsafe
For a 64-bit build on Windows, pointers are 64-bits, while
long is 32-bits, so PTR2ul() discards some bits.

isnan (long double): always use the C99 version
C99 requires that isnan() is a generic macro that accepts the
standard floating point types (float, double, long double).
We always include math.h eventually, so this macro should be
available.
This is complicated by C++. C++98 depends on C89, which does
not require isnan(), but since we do require C99, I think we
need to require a minimum of C++11, which follows C99.
C++11 does *not* define isnan() as a macro, but as a set of
overloaded functions, which produces almost the same result,
the difference being that the macro test that was done by this
code is no longer valid.
The old code would fail to build with long double builds C++
builds with gcc on Window:

POSIX: mingw64 doesn't make the bessel functions visible with -std=c99
And doesn't provide a way to make them visible, even though they
are visible by default for MSVC UCRT builds.
The __MINGW32__ macro is set for both 32-bit and 64-bit MINGW builds.
