You can go to sunsite.unc.edu, the home of Linux code, and download the
DosLinux package that lets you set up a small Linux partition inside your
Dos system (using the UMSDOS/W95 file system).  You can then download the
latest gcc compiler for Linux and use it to test your portability issues.
You have a leg up using DJGPP, since it's supposed to have the same interface
and share many of the include files that the Linux version has.
