Here are the files that I added...

mpe/src/Makefile
mpe/src/tgetent.c
mpe/src/tgetflag.c
mpe/src/tgetnum.c
mpe/src/tgetstr.c
mpe/src/tgoto.c
mpe/src/ty.c
mpe/src/ty.o

Most of them are termcap stubs that are implemented by calling
the equivalent terminfo routine. The ty.c uses an MPE/iX intrinsic
to allow switching HPTYPEAHEAD on or off.


Here are the files that have been adjusted...

Makefile.in
config.guess
config.sub
configure
install-sh
Makefile.in
info/terminal.c
makeinfo/makeinfo.c
makeinfo/Makefile.in

The changes are fairly small, only a few lines per file, except
for the configure script, that has been re-generated with MPE/iX
specific callci-extensions by using GNU autoconf for MPE/iX.

Download the gi-mpe.tar.Z and examine the mpe/diff* files for
details. Below are only a few "more interesting" diff snippets:

a) How to capture termcap routines "before" libcurses.a
b) Where to enable HPTYPEAHEAD for single-byte reads of Esc stuff
c) Disabling of setlocale() for LC_MESSAGES (not avail on MPE)
