Changes needed to support WinCE compilation:

Don't try to raise SIGABRT if not defined.
Return from fips_dhvs.c main instead of calling exit.
Workaround for lack of GetSystemFileAsFileTime.
Disable optimisation for part of bn_nist.c to avoid compiler bug.
Remove /WX flag so we don't exist on warnings.
