So you do indeed have long double...

The defines come from idlpython.cc in the IdlPyPlatformDefines function,
where it just sets the defines according to what's set when that file is
compiled. Something somewhere is preventing HAS_LongDouble from being
set, or is undefining it once it's set. I wonder if Python.h is doing
something that prevents SIZEOF_LONGDOUBLE being right. All I can suggest
you do is to add some things to the files being #included to trace why
HAS_LongDouble is not set when idlpython.cc is compiled.

Cheers,

Duncan.
