Autotools provides a standard interface for the compiler of a library as well as a method of installing the library. This is useful to packagers and people who need to develop their software against libsquirrel. pkg-config files for libsquirrel and libsqstdlib enable programs which use squirrel and their developers to easily add squirrel to their build environment.
Grab an autotoolized copy of squirrel from http://ohnopub.net/hg/SQUIRREL2 . If people are interested in having a Mercurial ( http://mercurial.selenic.com/ ) copy of squirrel, I am willing to go back and reconstruct a bit of version history by downloading the old tarballs. Please just ask ohnobinki to do so.
hg clone http://ohnopub.net/hg/SQUIRREL2
This patch is in use in Gentoo's ebuild for squirrel:
http://sources.gentoo.org/viewcvs.py/gentoo-x86/dev-lang/squirrel/ ( for https://bugs.gentoo.org/169051 )
The version of Squirrel in this GNU Arch (http://wiki.gnuarch.org/) repository also uses GNU Autotools for build.
