I think you can use the chdir function in DJGPP to do that.  For example, 
instead of _chdrive(3) you should say chdir("c:."), instead of 
_chdrive(1) say chdir("a:."), instead _chdrive(0) say chdir("."), etc.

(chdir in DJGPP's library changes drives as well as directories, unlike 
other compilers.)

Not according to my references.  I think _chdrive actually changes to the 
named drive and returns non-zero if it couldn't.  chdir does the same in 
DJGPP.
