VL: I couldn't reproduce a single warning when enabling these macros
with icc 10.1 20080212 on Itanium. But with this version, __ICC isn't
defined (__INTEL_COMPILER is, though), so that these macros are enabled
anyway. Checking with other ICC versions is needed. Possibly detect
whether warnings are produced or not with a configure test.
+ Remove C++ too, since it complains too much. */
/* Added casts to improve robustness in case of undefined behavior and
compiler extensions based on UB (in particular -fwrapv). MPFR doesn't
use such extensions, but these macros will be used by 3rd-party code,
where such extensions may be required.
Moreover casts to unsigned long have been added to avoid warnings in
programs that use MPFR and are compiled with -Wconversion; such casts
are OK since if X is a constant expression, then (unsigned long) X is
also a constant expression, so that the optimizations still work. The
warnings are probably related to the following two bugs:
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=4210
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=38470 (possibly a variant)
and the casts could be removed once these bugs are fixed.
Casts shouldn't be used on the generic calls (to the ..._2exp functions),
where implicit conversions are performed. Indeed, having at least one
implicit conversion in the macro allows the compiler to emit diagnostics
when normally expected, for instance in the following call:
mpfr_set_ui (x, "foo", MPFR_RNDN);
If this is not possible (for future macros), one of the tricks described
on http://groups.google.com/group/comp.std.c/msg/e92abd24bf9eaf7b could
be used. */

/* Check if <stdint.h> / <inttypes.h> is included or if the user
explicitly wants intmax_t. Automatical detection is done by
checking:
- INTMAX_C and UINTMAX_C, but not if the compiler is a C++ one
(as suggested by Patrick Pelissier) because the test does not
work well in this case. See:
https://sympa.inria.fr/sympa/arc/mpfr/2010-02/msg00025.html
We do not check INTMAX_MAX and UINTMAX_MAX because under Solaris,
these macros are always defined by <limits.h> (i.e. even when
<stdint.h> and <inttypes.h> are not included).
- _STDINT_H (defined by the glibc), _STDINT_H_ (defined under
Mac OS X) and _STDINT (defined under MS Visual Studio), but
this test may not work with all implementations.
Portable software should not rely on these tests.
