- These patches to bison 1.19 remove all references to the macro USG from the
- bison source code. This macro is obsolete, and usage of it has been
- inconsistent. It has been replaced by two specific checks, for <string.h>
- and <memory.h>. The bulk of these patches are changes to the configure
- script, which should be regenerated from configure.in anyway.
-
- Yours for cleaner code.....

- david d 'zoo' zuhn | There is great disorder under the heavens,
- cygnus support | and the situation is excellent.

- +
- + * conflicts.c: use HAVE_MEMORY_H instead of USG for <memory.h>,
- + remove test for USG by <alloca.h>
- +
- + * getopt.c: remove test for USG for <alloca.h>
- +
- + * system.h: rework so that testing for USG is no longer needed
