-/* This header provides an implementation of the type-generic issignaling macro.
-   Some points of note:
-
-     - This header is only included if the issignaling macro is not defined.
-     - All targets for which Fortran IEEE modules are supported currently have
-       the high-order bit of the NaN mantissa clear for signaling (and set
-       for quiet), as recommended by IEEE.
-     - We use the __*_IS_IEC_60559__ macros to make sure we only deal with formats
-       we know. For other floating-point formats, we consider all NaNs as quiet.
