glr.cc, yacc.c: initialize yylloc properly
There are several issues to address here. One is that yylloc should
be initialized when possible. Another is that the push parser needs
to update yypushed_loc when the user modified it. And if the parser
starts by a reduction of an empty, it uses the first location on the
stack, which, therefore, must also be initialized to this initial
location.
This is getting complex, especially since because initializing a
global (impure interface) is different from initializing a local
variable. To simplify, the local yylloc is not initialized during its
definition.

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.
