#24 keyboard-editor fails to build on F9

[Michael J. Hammel]

I'm trying to compile keytouch-editor on Fedora 9 and could use a little
help. Keytouch builds okay but I'm having problems with keytouch-editor
(my keyboard - Logitech S510 - appears supported but I didn't know that
till after trying keytouch-editor, then building and installing
keytouch) . I've tried with both the default GCC 4.3 and have also
installed GCC 3.4. Both return the same error:

This is also happening on Ubuntu 8.04 and 8.10 x64.

I see exactly the same build error with keytouch-editor-3.2.0-beta on Ubuntu 9.04 (Jaunty).

It looks like a straightforward source-code bug.
