   Does anyone know how to unset an environment variable in Turbo C
2.0?  I've tried code of the form:

putenv ("foo=");

but it just changes the entry for foo to say

foo=

and I can't find any other functions that make changes to the environment.
Do I have to go in and play around with the environment pointers
directly?
