[Bug fortran/34432] integer(kind=init_expression) function is rejected

["burnus at gcc dot gnu dot org" <gcc-bugzilla@gcc.gnu.org>]

The problem for (...) expressions is:

In match_primary, several gfc_match_* are called, which all return MATCH_NO,
until  gfc_match_char ('('), which returns true. (So far so good.)

However, before "gfc_match_char" there is a call to gfc_match_rvalue.
gfc_match_rvalue calls gfc_match_name -- and the latter not only returns
MATCH_NO, but also issues

      if (gfc_error_flag_test() == 0)
        gfc_error ("Invalid character in name at %C");

which is at the heart of the problem. Without the call to gfc_error, the
program works.

The next question is how to solve this without breaking the diagnostics. I'd
assume this affects much more expressions than this one.

I was thinking of a flag (like "bool match_only"), which means that on needs to
audit all 37 uses of gfc_match_name.
