I'm wondering how I go about substituting GNU malloc for BSD malloc(). I have the XFree86 3.1 link kit for FreeBSD 2.0, and the XFree86 3.0 source tree on a Walnut Creek X11R6 CD-ROM. I wasn't able to find any way to replicate what you did. I'm actually interested in rebuilding just about everything to use GNU malloc(). I'm a fanatic about this. I've already rebuilt the entire /bin and /sbin directories to use shared libraries, even init! It works fine, but from David Greenman's complaints about shared library RAM usage, I'm not sure that it really accomplishes much, since it only saves a couple of MB on the disk. The interesting point is that I've never been able to detect any performance degradation from having done that! Of course, I run a lightly loaded desktop machine, not a server running a lot of scripts.
