tktable 2.7 mac patches & binary

Attached a small patch to the HEAD that was needed to
get 2.7 to compile cleanly on the mac.

The codewarrior project in cvs tktable/mac seems to be
corrupt, maybe it hasn't been added with option -kb ?

I've attached a project I've recreated from scratch, and
also an xml version of the project, which is utf8 and
thus probably safer and potentially more useful (small
edits should be doable without having access to
codewarrior)

also attached a ppc-only binary of version 2.7

all text files in latin1 encoding, mac users need to
convert before using but unix users can checkin the
attached files as is and mac cvs clients will then
checkout correctly.
