This fixes an issue with bash implementing a flag introduced by later
versions of glibc (around 2.3.4) which, in turn, is not supported by
earlier revisions of the Linux kernel (pre-2.6).  This causes an
infinite loop when Bash is run interactively and a child process
such as "ls" or "grep" exits.  Please see:
http://lists.gnu.org/archive/html/bug-bash/2005-05/msg01408.html

I prefer this patch to the one provided by the LFS project since,
as the author states, it only must perform the check once and it
is compatible across platforms.  It also doesn't use goto
statements.  :)

This patch has been patched by hand to allow for proper automatic
application with the Bash.SlackBuild script in the parent
directory.
