Re: Recent changes to regex.c break bootstrapping

[Chong Yidong]

The 2006-02-19 change to regex.c, changing malloc and realloc to
xmalloc and xrealloc, doesn't do what it is apparently supposed to do,
since regex.c defines malloc as xmalloc, realloc as xrealloc, and free
as xfree when linked with Emacs.  For the case when it is not linked
with Emacs, I added xmalloc and xrealloc definitions (no need for
xfree, since its only purpose is to call BLOCK_INPUT), and put in the
same malloc -> xmalloc, realloc -> xrealloc redefinitions.

I hope this is correct way to go.  One worry: if another
non-Emacs-linked file #includes regex.c and defines its own xmalloc,
ugliness may ensue.
