Previously in the imake world, changing the CDE version required hand
editing a handful of files.
This commit makes these files into ".in" files. configure.ac now
holds CDE version information -- both in the AC_INIT() call and in the
CDE_VERSION_* variables a few lines down.
Changing the CDE version now involves editing those two locations in
configure.ac only.
Thereafter, a configure run will replace version information in the
following files with the current CDE version:
copyright
doc/common/help/HELPEnt.sgm
include/Dt/Dt.h
lib/tt/bin/ttauth/ttauth.man
This also causes a catch-22 problem with ToolTalk. So the
tooltalk.inc file is gone and the relevant TT Makefiles have been
modified to set and define the TT version in those Makefiles that
actually use it.
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.
Some files were trying to access the global includes directy in the
build area with things like #include <api/c/tt_c.h>, which is now
wrong. Se we fix all of those up. tt_c.h and tttk.h are now global,
so we no longer need to root around various build dirs to find them.
TT builds again.
