Dear Sir,

Excuse me this stupid question, but where can I find this file
(src/leb/libc/stdlib/malloc.c from -current to rebuild a libc) without
having to d/l all of the FreeBSD-3.0 tree? (I would like to install 
XFree86-3.3 with my 2.2.2-RELEASE, and preferably without a problems 
with compilation)

Thanks in advance.
