I have poked at this for a while, and found one of the most WHACKO
make problems that I have encountered in a long time.

   The top level Makefile is invoked with  'make solaris'
Make will then do:
(cd SunOS5/whateverhorriblesystem; make build TOP=../.. 'MFLAGS=-I$(TOP)' ....)
(cd SunOS5/whateverhorriblesystem; make -f Makefile.whatever build ....)

In the Makefile.whatever we find:
      cd $(TOP)/iplang; $MAKE $(TOP)/iplang

And we soon see:
      gcc -I(TOP) ...

As reported, this dies with a horrible error,  due to the fact that
there is no (TOP) directory...  I guess.

Now a bit of detective work soon leads you to the conclusion that what
is happneing is that the line started with:
      gcc $(CFLAGS) 
CFLAGS was '-I$(TOP) ...' in the previous makefile invocation,
but for some reason (which I know,  but don't even want to start to
try to explain), it does not get passed correctly into the environment
of either make or the gcc compiler.

You can FORCE the right value by sticking it onto the end of the line:
      cd $(TOP)/iplang; $MAKE $(TOP)/iplang CFLAGS=-I..

Enjoy.  Don't ask why.  It is UGLY.
