59a63247992eb13153b82c4902aadf111460eac2 Fortran: fix treatment of character, value, optional dummy arguments [PR107444]
Fix handling of character dummy arguments that have the optional+value
attribute. Change name of internal symbols that carry the hidden presence
status of optional arguments to distinguish them from the internal hidden
character length. Update documentation to clarify the gfortran ABI.
gcc/fortran/ChangeLog:

to all intrinsic types, and change prefix of internal symbol to '.'.

create_function_arglist.
(gfc_conv_procedure_call): Fix generation of procedure arguments for
