Hello world,
the attached patch does what it says in the ChangeLog entry.
Tested with "make dvi" and "make pdf".
OK for trunk?
Best regards
Thomas
Document unsigned constants in intrinsic modules.
gcc/fortran/ChangeLog:
* intrinsic.texi (ISO_FORTRAN_ENV): Also mention INT8 in the
text. Document UINT8, UINT16, UINT32 and UINT64.
(ISO_C_BINDING): New table for unsigned KIND numbers.
