It was used in gcc-2.95.X but it's nightmare to get all makefiles and
configure to operate normally when one has to get $DJDIR through without
expansion.  

When You're building for example Linux to DJGPP cross-compiler You are
giving Linux specific prefix like /usr or /usr/local so this all doesn't 
matter.

For Canadian cross builds (like building native compiler for DJGPP or
DJGPP hosted cross-compiler under Linux) one can safely specify in prefix
/dev/env/DJDIR and nothing should break.

For example I'm specifying /dev/env/DJDIR as prefix when I'm building 
native binutils for DJGPP under Linux.
