But the current way is also not Unix-like, and not what you would
expect by reading the gcc docs. Let me summarize the two situations, 
where the letters in front of the directory names mean the class of
directory:

1) Unix search order in the default gcc installation (/include and /lib
subdirs in each of these will be searched), rough outline: 

a) $(C_INCLUDE_PATH) or $(LIBRARY_PATH)    -- (if set)
b) /usr/local/lib/gcc-lib/i586-linux/2.7.2
c) /usr/local  -- maybe
c) /usr

2) DJGPP, current setup, with gcc-2.81:
a) $(DJDIR), via setting of $(C_INCLUDE_PATH) and $(LIBRARY_PATH)
b) $(DJDIR)/gnu/gcc-2.81 
c) /usr -- usually inexistant!

So my question is this: why not change the default DJGPP.ENV and
make DJGPP versions of gcc automagically use $(DJDIR) whenever
they would normally use /usr, i.e. use the DJGPP directory
in class 'c)', not 'a)'?
