To compile 0.01 on your machine, you'll probably need -I/usr/ego/include 
and -I/usr/ego/include/gtk .

I agree, and have changed all of the #include directives to reflect this
suggestion.  It now builds on my system with just -I/usr/local/include .
This is a major improvement. Thanks, Otto!

I'm glad...

   Stepping back for a moment, I've noticed that a lot of the problems 
people are talking about on this list have to do with using simple.c as 
the "hello world" template for building apps. However, simple.c has a lot 
of things wrong with it:

+ #include "gtk.h" rather than #include <gtk/gtk.h>

+ signal handlers call gtk_exit (0) rather than gtk_main_quit ()

+ both signal handlers quit

+ no separate build process

   I've put a tentative hello world example up at
http://www.levien.com/gimp/hello.html .

One thing this example is sorely lacking is an autoconf script. I have no 
idea how to go about building one, but if anyone else here knows how and 
would be willing to contribute, I'd be happy to put it on the page.
