Please show at least one example of your `depend' targets, it's very hard 
to help you without seeing how you invoke the compiler.

I don't think so.  I suspect that it's the result of adding this to 
specs:  -imacros %s../include/sys/version.h.
Please try editing this out of specs and see if the problem goes away.  

Even if editing specs solves the problem, I don't think it's a solution, 
because -imacros is there for a reason (so that even in a program that 
doesn't include stdio.h __DJGPP__ and __DJGPP_MINOR__ are defined 
correctly).  Perhaps GCC has some switch that makes it ignore headers 
which come through -imacros.  If not, perhaps we need to ask for such a 
switch.  (Or perhaps you could view this as a feature: a different libc 
version does require to recompile, right? ;-)
