While trying to do a make for the openssl 0.9.6a i had an error that the
file termio.h is missing.
Well, it looks like there is a missing include line in one of the make files
in the crypto/des library.
The missing line causeing the make to fail in qnx6 system, i guess i could
be on qnx4 too.
Anyway, you should add -I/user/include/sys
to the following make file: openssl0.9.6a/crypto/des/Makefile
