[PATCH] configure.ac and cxx-type.at patches for bison-1.49c

[Art Haas]

Hi.

The configure.ac patch converts AM_CONFIG_HEADER to AC_CONFIG_HEADERS
as automake-1.7 has obsoleted its version. Also, the configure
template still used the old AC_OUTPUT format, so I switched it to
use AC_CONFIG_FILES and then call AC_OUTPUT.

The cxx-type.at patch fixes a missing "=" error.

I'd like to  suggest modifying the main() routine here slightly. I
typically build with '-DNDEBUG' used to compile files, and in this
test, the freopen() call is contained within the assertion. When
I build with the assertion-killing flag, the testsuite hangs at
the first cxx-test, because the freopen() call has disappeared!
Maybe something like this ...

int
main (int argc, char ** argv)
{
   if (argc != 2) return 1;
   if (!(freopen(argv[1], "r", stdin))) return 1;
   return yyparse();
}

Having the freopen() call in the assertion may/will trip up other
people who build bison with the -DNDEBUG flag and run the test suite.

The 1.49c build went cleanly and all the tests passed on my
machine. I'm building on i586-pc-linux-gnu.

Thanks.
