This is going to matter only if you use Windows 95:
Aside from noting that the DJGPP.ENV setting for these variables pulls
in what's already defined in the ambient, let me also mention a
wonderful little utility on the Windows 95 CD called "winset.exe".
This command resets environmental variables in the current DOS box AS
WELL AS in the master Windows 95 environment (so that the next DOS box
you pull up will have the changed environmental variables.)
Create two batch files djgppvar.bat and othergcc.bat that defines the
appropriate environment variables with winset.exe, bring them to the
desktop (maybe making them run minimized). Double click on the
djgppvar.bat icon, open your djgpp DOS box; then double click the
othergcc.bat icon, and open your other GCC DOS box. And you have two
DOS boxes with two different sets of environments!
Hope that helps.
