There are some hacks in gcc.c from gcc-2.96 snapshots to get gcc binaries
which can be installed anywhere (prefix is determined at runtime from actual 
location of gcc executable). This relative prefix overrides the default
one which is $DJDIR (of course)

For the other side gcc/prefix.c substitutes environment variable at start
of some file location only if it begins with prefix (which now is
determined at runtime and of course doesn't more begin with $DJDIR)

I see 2 possible solutions:

	- forcing always substitute environment variable $DJDIR
          (of course for DJGPP only: #ifdef __DJGPP__)

	- disabling looking for relative prefix for DJGPP 
	  (also ifdef-ing corresponding code out in gcc.c out for DJGPP)

PS. There is no similar problems with gcc-2.95.2. And also the problem
    with LD_LIBRARY_PATH can remain unnoticed unless one removed
    definition of this enviroment variable from DJGPP.ENV
