Newer OS/2 support patch

[Ilya Zakharevich <ilya@math.ohio-state.edu>]

This patch almost makes it: this time I tested installation also, and
it needs only instertion of two carriage returns in the
install-include section (somehow they are stripped by sh) to work.

(Note that a patch to fix a filedescriptor leak is needed too.)

Enjoy,
Ilya
