sets __STDC__ to 0, but requires "##" for token pasting.
_AIX - gnu ansidecl.h asserts that all known AIX compilers are ANSI but
don't always define __STDC__.
_mips - gnu ansidecl.h says the RISC/OS MIPS compiler is ANSI in SVR4
mode, but doesn't define __STDC__.
_MSC_VER - Microsoft C is ANSI, but __STDC__ is undefined unless the /Za
option is given (in which case it's 1).
_WIN32 - tested for by gnu ansidecl.h, no doubt on the assumption that
all w32 compilers are ansi. */

/* __GMP_DECLSPEC supports Windows DLL versions of libgmp, and is empty in
all other circumstances.
When compiling objects for libgmp, __GMP_DECLSPEC is an export directive,
or when compiling for an application it's an import directive. The two
cases are differentiated by __GMP_WITHIN_GMP defined by the GMP Makefiles
(and not defined from an application).
__GMP_DECLSPEC_XX is similarly used for libgmpxx. __GMP_WITHIN_GMPXX
indicates when building libgmpxx, and in that case libgmpxx functions are
exports, but libgmp functions which might get called are imports.
libmp.la uses __GMP_DECLSPEC, just as if it were libgmp.la. libgmp and
libmp don't call each other, so there's no conflict or confusion.
Libtool DLL_EXPORT define is not used.
There's no attempt to support GMP built both static and DLL. Doing so
would mean applications would have to tell us which of the two is going
to be used when linking, and that seems very tedious and error prone if
using GMP by hand, and equally tedious from a package since autoconf and
automake don't give much help.
__GMP_DECLSPEC is required on all documented global functions and
variables, the various internals in gmp-impl.h etc can be left unadorned.
But internals used by the test programs or speed measuring programs
should have __GMP_DECLSPEC, and certainly constants or variables must
have it or the wrong address will be resolved. */
