The purpose of djgpp was to port the GNU C/C++ compiler to a 386/DOS
environment, specifically to take advantage of the 32-bit instructions
and address space.  80286 machines simply do not have the
functionality required to implement such a port, and are not supported
(probably never will be, either).  The major obstacle is the GCC
compiler itself, which assumes a 32-bit "int" and 32-bit address space
- see their documentation for why they did this.

It is important to use binary mode when transferring these files
around, as they are binary chunks of a binary file.  PKZIP version
1.01 (I think) was used to create this file, and the -d option must be
used to un-zip it properly, as per the readme file.
