Such environments are missing void type, older K&R C, and
such supports already had been removed in various places.
Furthermore, current hardcoded 'SIGNALRETURNSINT' is wrong.
With this patch, CDE (autotools) builds and runs on fbsd 12 now.
fbsd11 should work too, but not yet tested.
You must use gmake - ie:
./configure MAKE=gmake
gmake
Seems all of the BSD's will need to use gmake for now.
Certain programs like dtlogin and tt_type_comp need access to the
system's cpp command to process certain files at runtime. tradcpp is
not installed on most systems, and is intended for use as a imake-cpp
replacement which is all we are using it for. We still need an
honest cpp for the CDE components to use.
Now, we look in various places for a 'cpp' command and set CPP_COMMAND
to it's value. This way tt_type_comp and other CDE programs can do
required processing at runtime.
Also, restructure some of the dependencies in the lib/tt binaries. We
will link with libtt (which will include libtirpc as a dependency),
and XTOOLLIB - all the right X11 stuff without needing to add it to
every OS. Removed several uneeded OS specializations ("if LINUX",
etc) as a result.
That was not fun. There were a variety of issues. It's needs
testing.
We use the new GENCPP for preprocessing the various scripts and config
files in config/
