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.
