Don't know if this is (supposed) to work, but if just the DJGPP
variable is of concern, maybe a putenv("DJGPP=k:/abcd/djgpp.env") in
your IDE might work? Then programs spawned by the IDE should use
this[1]. If it works it is easily extended to any variable you want.
It only works with programs spawned from the IDE though.

hth,
 Robert.

[1] I am unsure if this works, but i think it should, at least it
    works under solaris. with the following test program (tes.c):
/* -*- mode: C; compile-command: "gcc -Wall -o tes.exe tes.c" -*- */
/* quick and dirty get-/putenv test by rjvdboon AT cs DOT vu DOT nl          */
#include <stdlib.h>
#include <stdio.h>
int main(int argc, char **argv) {
  char *t;
  if (argc > 1) {
    printf("%s option: %s\n", argv[0], argv[1]);
    t = getenv("TST1TST");
    if (t) {printf("%s\n", t); }else{ printf("no TST1TST"); }
  } else {
    printf("putenv + system:\n\n");
    putenv("TST1TST=JaEnzoEnv");
    system("tes jaja");
    printf("\nsystem done\n");
  }
  return 0;
}
