fix comment
The "shadows a global declaration" warning in GCC 4.0 was a bit
annoying. It does not like that a type name be used in a prototype of
a function (not the implementation, just the declaration):
In file included from src/LR0.c:38:
src/reader.h:56: warning: declaration of 'named_ref' shadows a
global declaration
src/named-ref.h:35: warning: shadowed declaration is here
It does not like either when a global variable name is used in a
prototype. Flex 2.5.37 generates this prototype:
void gram_set_debug (int debug_flag );
* src/getargs.h, src/getargs.c (debug_flag): Rename as...
(debug): this.
Adjust dependencies.
* src/reader.h: Don't use "named_ref" as a formal argument name.
Fix the following warning
parse-gram.c:2078:14: error: equality comparison with extraneous parentheses
[-Werror,-Wparentheses-equality]
if (((yyn) == (-91)))
~~~~~~^~~~~~~~
parse-gram.c:2078:14: note: remove extraneous parentheses around the
