The config.h file generated by autoconf is intentionally not installed. 
If you need info about octave configuration, there is octave-config.h 
which is installed.  If you need the info about OS features that is 
found in config.h, you need to do your own configuration and generate 
your own config.h file appropriate for your source files and build system.

For the communications package specifically, I would start by looking at 
the patches for it that are part of mxe-octave.  I expect they already 
deal with most build issues that you are seeing when trying to build it 
with a current version of Octave.
