Re: Merging forked versions of regex.c

[Richard Stallman]

    Unfortunately, this task is now harder because glibc has recently
    adopted a new (completely rewritten) regex implementation, which is
    presently unusable by emacs (re_search_2 is implemented by mallocing a
    buffer to hold the two strings, copying them into it, and then
    searching!!!).  Also, Tom Lord has examined it, and he claims that it
    has other serious problems that make it currently unsuitable for general
    use [I haven't seen any response to this].

People will have to study whether those problems are true.  Supposing
they get fixed, how hard is it to modify the code to work for Emacs?
Could you study that?
