Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
difficult and introduced a lot of core dump. It turns out that
Bison used an implementation of `xmalloc' based on `calloc', and
at various places it does depend upon the initialization to 0. I
have not tried to isolate the pertinent places, and all the former
calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
someone should address this issue.
* src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.

order to get rid of the `static' prototypes.
No longer use `register'.

Propagate its inclusion in files explicitly prototyping functions
from output.c.

Let all `extern' declarations about getargs.c be replaced with
inclusion of `getargs.h'.

HAVE_GETTEXT, HAVE_LC_MESSAGES, HAVE_STPCPY): Remove, handled by
autoheader.
* Makefile.am (SUBDIRS): Add m4.
