Ok - so one of the steps in building CDE is an early phase called the includes phase (make includes). At this point, all of the public header files are exported to exports/include/Dt, DtI, ... Then, the software is built using that include dir. This of course does not work in autotools. Much of the software does things like #include <Dt/something.h>, so in order for the build to succeed, this behavior must be represented/replicated in some way. It seems the usual way of dealing with this is to place all public headers (and in some projects, ALL headers) into a toplevel include directory. We now do this for all public headers - they have been moved from wherever they were and placed in the appropriate spot in includes/ This will break the Imake 'make includes' phase unless the Imakefiles are fixed (remove the HEADERS = stuff, and the incdir defines). This has not been done at this point since in reality, once autotools works properly, there will be no need for the Imake stuff anymore, and I intend to get rid of it. This is just a warning for now - Imake builds in this tree will now fail at the 'includes' stage. This commit is only the migration. In upcoming commits, libtt will be fixed so that the hack being used before to get around this problem is removed as there will no longer be any need. And then the autotools work continues...
