[PATCH] commited fix to _INTEGRAL_MAX_BITS define on mingw32

[Danny Smith]

Committed as obvious.  See
http://msdn2.microsoft.com/en-us/library/b0084kay(VS.80).aspx
where _INTEGRAL_MAX_BITS is documented as:
"Reports the maximum size (in bits) for an integral type."

	PR target/31965
	* config/i386/mingw32.h (_INTEGRAL_MAX_BITS): Define builtin as
	TYPE_PRECISION (intmax_type_node).
