This is in general not possible without using undocumented DOS 
structures.  There is no library function in DJGPP that implements such 
functionality (`setenv' and `putenv' aren't supposed to do that, they 
only change the environment of the calling program and all the programs 
it spawns).

Call pushd/popd from a batch file.  A batch file can set an environment 
variable in its shell.

First, get the latest version of bash, such problems get constantly 
corrected there.  (An announcement was posted here about bashb6.zip just 
a day ago.)  If the problem persists, post a detailed description here: 
the author of the bash port reads this news group and will either suggest 
a solution or fix the bug.
