Re: [PATCH] Include "gdb_regex.h" instead of "gnu-regex.h"
Date: Thu, 2 Aug 2001 16:29:13 -0400
From: DJ Delorie <dj@redhat.com>
Why not "xregex.h" ?
I'm working on that :-). In fact replacing gnu-regex.{c,h} with
xregex.h is what prompted this change. We will still need to go
through gdb_regex.h to support --without-included-regex though.
Before we can get rid of the regex code in the gdb subdirectory, there
is one problem to solve though. GDB uses the BSD re_comp() and
re_exec() instead of the POSIX interfaces. Unfortunately, that bit of
code isn't currently compiled into the code included in libiberty.
In the long run we probably want to switch to the POSIX interfaces,
but in the meantime, the attached patch would make it possible to use
"xregex.h" in GDB. I think it is pretty harmless, although it does
involve some name-space pollution.
