I added this because I didn't run `autoconf' or `autoheader, it was
mentioned in my message.  Of course it should be replaced with a proper

Also, drawing code is not portable and was adapted from some existing
code for X.  Don't remember which exactly.

AFAIK, librsvg tests for pkg-config in its own `configure' script.
