The feature of decimal-floating-point isn't enabled in gcc for
cygwin/mingw targets. Question for those targets are, which
decimal-floating-point variant should be used, is there any support by
runtime, which ISO-Spec it the Decimal128 type in #c following? etc.
As long as those points aren't clarified I don't want to enable this
feature for win32.

Kai
