The situation essentially is the same as in December 2005: I tried
build with 4.2 and I fixed a bunch of problems.  But then I noticed
that backend folks removed support for character type from the backend.
So proper port to 4.2 should internally use integer type to represent
Pascal character type.  This is not very big change, but also not
a trivial one.  At that time I decided to suspend 4.2 port and concentrate
on 4.1.   I can not what more is strictly necessary for 4.2 port,
usually most porting effort goes into fixing new bugs and that is
of course very unpredictable.

Let me clearly say that ATM I am _not_ working on 4.2/4.3 port
-- currently most of my programming effort goes into computer
algebra, more precisely FriCAS:

Also, there are few things which strictly speaking are not neccessary
for 4.2 port, but which probably should be done first (like changing
sets implementation).
