[PATCH] Use AT_DATA_GRAMMAR for C++ compile test for variants

[Di-an JAN]

This patch uses AT_DATA_GRAMMAR instead of AT_DATA for C++ compiled tests
as requested by the comments to AT_DATA_GRAMMAR_PROLOGUE in tests/local.at.

Fixes tests 198-202.  The failure mode on Cygwin is:

The header <string> pulled in <string.h>, which, because of CPPFLAGS in
tests/atlocal.in, used the gnulib version in lib/string.h, but that,
on Cygwin, declared ``stpcpy'' using ``restrict'' unconditionally, which,
according to the lastest GCC manual, is not a C++ keyword.  The configury
to handle that is in lib/config.h, which is not used by lib/string.h,
but is included when using AT_DATA_GRAMMAR.

Patch tested on Cygwin with ``make check'' with one expected failure.



By the way, I'm wondering we should do testing using gnulib headers in lib/
or should we test that Bison-generated programs can be compiled without
using gnulib.  Patch ``no-config.patch'' attached for experimenting.
No problems on Cygwin.
