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].

Is it true that nothing can be known?  If so how do we know this?  -Woody Allen
