re PR target/32641 (C99 fpclassify, isinf, isfinite, isnormal may raise FP exceptions)

fixincludes:
	PR target/32641

	* inclhack.def (solaris_math_4, solaris_math_5, solaris_math_6,
	solaris_math_7): Constify and make FP exception-safe.
	* tests/base/iso/math_c99.h: Update.

	* fixincl.x: Regenerate.

gcc/testsuite:
	* gcc.dg/c99-math-double-1.c: Mark test variables as volatile.
	Test negative numbers also.
	* gcc.dg/c99-math-float-1.c: Likewise.
	* gcc.dg/c99-math-long-double-1.c: Likewise.
	* gcc.dg/c99-math.h: Check for FP exceptions.  Update for negative
	test inputs.
