Danek,

Can you check that you can reproduce the bit about failing to detect
tcsetpgrp properly?

If you can reproduce it, can you then try this patch and see if it
fixes the configure problem? You will need to regenerate the configure
script by running "autoconf" after patching zshconfig.ac.

BTW, I could not reproduce your problem at all. If I run configure in
the background, it just stops during the "checking if tcsetpgrp()
actually works..." test. This patch fixes this part.

Thanks,
Phil.
