A few years ago I looked at libgnumalloc briefly, and found that
% grep -Ri gnumalloc /usr/src /usr/xsrc
seems to reveal that there are no actual users of libgnumalloc in our
current tree.. the XFree86 and Xorg NetBSD.cf files disable it for
NetBSD>1.4J, and pkgsrc showed nothing explicitly referring to it.
The README file says
| This is the standalone distribution of GNU malloc.
| GNU malloc is part of the GNU C Library, but is also distributed
| separately.
but looking at gnu.org I don't see that the latter is still true, and our
version is very old according to the VERSION file
| this version of GNU malloc was obtained from
| prep.ai.mit.edu on 9/22/1993. There was no version noted."
..are there any known uses for this, is it time to remove it?
