Tutorial patch.

[johannes nada kth se (Johannes Keukelaar)]

Hi all,

Here's a small patch to the tutorial so that it will now say to use gtk-config 
when compiling. I don't have any sgml tools, so please do check the syntax.

I'll upload it to ftp.gtk.org as gtk-johannes-980319-1.patch.

Regards,

Johannes.
