Subject: [ruby-core:36417] Re: [Ruby 1.9 - Bug #3924] Performance bug (in require?)

I'll try to dedicate some time to helping on this but I can't promise
anything.   I'll take a longer look at Xavier's work later tonight or
tomorrow.

However, I needed the following trivial patch to build with gcc 4.4.5
on Debian:

diff --git a/variable.c b/variable.c
index 551a7d5..908a649 100644
--- a/variable.c
+++ b/variable.c
