Apple does not allow '==[c]'. So I have to use 'MATCHES[c]' for
case-insensitive,
but due to the regex, MATCHES is not implemented in GNUstep.
So I have no away to do case-insensitive full string comparison on GNUstep
excepting using a combination of 'BEGIN[c]', 'IN[c]' and 'END[c]' for that.
It is just less convenient.
Maybe for current situation, you can implement MATCHES as simple
full string comparison ?
It is the same as regex without all the special symbol (*, ?, [, ]).

Thanx. I will try again later.
Just confirm that NSPredicate works except the %d.
But it is not a big issue and can easily work around.
Thanx.
