To add some comment here:

Basically, this is the way to tell configure where your jpeglib.h
or libjpeg.a is.  If it's in /usr/local/include/jpeglib.h and
/usr/local/lib/libjpeg.a, and your gcc doesn't search these paths by default
(FreeBSD's and Solaris's apparently don't), then you would have to
set these variables before invoking configure, like so

	setenv CPPFLAGS '-I/usr/local/include'
	setenv LDFLAGS '-L/usr/local/lib'

and then call configure.  (Actually, you can also set CC to something like:
	setenv CC 'gcc -I/usr/local/include -L/usr/local/lib'

That is the "official", "GNU-blessed" way of doing it, and Alexandre's
patches allow Kaffe to follow these rules.

We will, however, put a patch in place that makes configure a bit
smarter by making it look in places where things like libjpeg often
reside, such as /usr/local.  (In fact, the AC_PATH_X macro is a 
macro where configure does just that: probing and guessing where the
X headers would be)

BTW, the probable reason this hasn't caused problems at Transvirtual
is that their main platform is Linux, and Linux's gcc apparently includes
/usr/local/include|lib in its include/library path.

The README file lists IRIX as "some code which used to work but has now 
fallen behind recent changes."  Of course, Transvirtual's web site is
a different issue... ;-)

 One possible drawback: would you still be able to simply type:
"gdb kaffe" or "gdb Kaffe"?
