avoid including gnulib header in installed Octave header file (bug #40607) * oct-conf-post.in.h (OCTAVE_ENSURE_LONG_DOUBLE_OPERATIONS_ARE_NOT_TRUNCATED): New macro. * oct-inttypes.h, oct-inttypes.cc: Don't include fpucw.h from gnulib or the macros it defines. In functions that need to ensure that long double operations are not truncated to double precision, use external functions.
