[PATCH] Replace a few AM_ macros with AC_ equivalents

[Art Haas]

Hi.

Here's a small patch that switches two AM_* macros to their AC_*
counterparts ...

AM_PROG_LEX ==> AC_PROG_LEX
AM_C_PROTOTYPES ==> AC_C_PROTOTYPES

I also added the AC_HELP_STRING macro as it seemed worthwhile.

        * configure.ac: Replace AM_PROG_LEX with AC_PROG_LEX,
        AM_C_PROTOTYPES with AC_C_PROTOTYPES, and format the
        --enable-gcc-warnings flag with AC_HELP_STRING.
