The initial location might be used if the parser starts by an empty
reduction, so really ensure proper initialization of the initial
location. The previous approach fails for PostgreSQL, which uses

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.
* data/c.m4 (b4_yyloc_default_define): Replace by...
(b4_yyloc_default): this.
Adjust dependencies.
* data/glr.cc: Initialize yylloc.
* data/yacc.c (b4_declare_scanner_communication_variables):
Initialize yylloc during its definition.
Don't define yyloc_default.
(yypush_parse): The location formal is not const, as we might
initialize it.
(yyparse): Define yyloc_default.
Use it before running the user initial action.
Possibly update the first location on the stack, and the pushed
location after the user initial action.
* tests/actions.at (Initial locations): Check that the initial
location is correct.
When generating a pure push parser, the initialization of yylval and
yylloc may not be visible to the compiler. With warnings enabled, GCC
4.3.6, 4.4.7, 4.5.4, and 4.6.3 report uninitialized uses of
yylval/yylloc. Using local pragmas to disable these warnings is not
supported before 4.6, and 4.6 does not support it properly. So
initialize yylval and yylloc at their definition. Reported by Peter
Simons. See

* data/yacc.c: Use it when locations are requested.
(YYLVAL_INITIALIZE): Replace by...

Therefore, remove the initialization of yylloc's field.
