	* gcc.dg/dfp/fe-convert-1.c: Expect FE_OVERFLOW when converting
	from 10.000000e96DD to _Decimal32, from 10.000000e96DL to
	_Decimal32 and from 10.00000000000000E384DL to _Decimal64.

	*  gcc.dg/dfp/fe-convert-2.c: Expect FE_INEXACT when converting
	from 1.0e96 and -1.0e96 to _Decimal32. Enable testing for
	converting from 1.0e-96 and 0.00048828125 to _Decimal32 when
	BID is used.
