Use strncasecmp to compare Fortran dot operations (like .AND.) and for the keywords list. This allows for some duplication to be removed from the token arrays. I've also performed whitespace cleanup around the code I've changed. I have added some tests to ensure that upper and lowercase dot operations are correctly tested. The keywords list remains always lowercase for now. There should be no user visible changes after this commit. gdb/ChangeLog: * f-exp.y (struct token): Add comments. (dot_ops): Remove uppercase versions and the end marker. (f77_keywords): Likewise. (yylex): Use ARRAY_SIZE to iterate over dot_ops, assert all entries in the dot_ops array are case insensitive, and use strncasecmp to compare strings. Also some whitespace cleanup in this area. Similar for the f77_keywords array, except entries in this list might be case sensitive. gdb/testsuite/ChangeLog: * gdb.fortran/dot-ops.exp: New file.
