Re: [RFC] Use HAVE_LONGLONG instead of __GNUC__ to check for long long support.

Daniel,

Used autoheader to generate the config.in file, but it does not look
pretty, also, removed the comments that you did not like.

2005-04-18  Manoj Iyer  <manjo@austin.ibm.com>
        * configure.ac: Added check for long long.
        * config.in: Regenerated.
        * configure: Regenerated.
        * words.h: Modified logic to check for HAVE_LONGLONG instead of
        __GNUC__, added config.h header file.


Please use AC_CHECK_TYPES, it should take care of defining
HAVE_LONG_LONG (note the extra underscore) and the comment all by
itself.
