Well, if it's non-portable and unreliable on *nix, you might get some
hate mail for breaking that. (Not that they don't always do it to us,
of course.) On those systems, I believe they make it a compile-time
constant or use env. var. to point to config directory (which is what
I assume you're trying to do).

Nobody mentioned that the DJGPP stub lets you fake something else,
e.g. "gunzip.exe" can be a very small 2 kb .EXE file that runs "gzip -
d" (as long as in same directory). That's one complication. Another is
probably the loading of the DJGPP.ENV file (mostly used by GCC itself
but also?? by user programs, I suppose).
