 356         * configure.in: Add calls to AC_CONFIG_HEADER, AC_CHECK_HEADERS,
 357         AC_CHECK_LIB, and AC_CHECK_FUNCS.  Change AC_OUTPUT to set
 358         stamp-h.
 359         * configure: Rebuild.
 360         * config.in: New file, generated by autoheader.
 361         * interp.c: Include "config.h".  Include <stdlib.h>, <string.h>,
 362         and <strings.h> if they exist.  Replace #ifdef sun with #ifdef
 363         HAVE_ANINT and HAVE_AINT, as appropriate.
 364         * Makefile.in (run): Use @LIBS@ rather than -lm.
 365         (interp.o): Depend upon config.h.
 366         (Makefile): Just rebuild Makefile.
 367         (clean): Remove stamp-h.
 368         (mostlyclean): Make the same as clean, not as distclean.
 369         (config.h, stamp-h): New targets.
