After consulting the gcc.gnu.org website some more, I discovered a
little blerb at the bottom of this page
http://gcc.gnu.org/install/configure.html
which mentions --with-headers=dir 
I added
--with-headers=/usr/local/compiler/cross/gcc-3.2/i686-pc-msdosdjgpp/include

which corrected the problem with MIN_LONG and PATH_MAX being
undeclared in getpwd.c and fibheap.c  

Yay, another hurdle crossed !!!  (and there have been lots)

and for the next hurdle...
'make' still terminates with these errors:
