[gnu.emacs.bug] fixes for emacs under aix386

TRANLE@INTELLICORP.COM (Minh Tran-Le) (12/03/89)

Here is some fixes to allow emacs 18.55 on aix386 to use the pty drivers for
emacs subprocesses. The ptys implementation on aix386 are similar to the bsd4.3
ptys. So here is some changes for the sysdep.c, process.c, m-ibmps2-aix.h,
Makefile .
The change to src/Makefile is just to allow the use of the gnu cpp if you
happen to use gcc to make the src/xmakefile.

Minh Tran-Le.
