Well, you didn't tell that in your message.  People don't normally
put random include files into c:\djgpp\include, so I thought that
file was in the same directory as tmp.c

Then it's probably a bug in GCC 3.0.3.

It defines two symbols, __DJGPP__ and __DJGPP_MINOR__, which tell
what is the version of the library you are using.  Some programs look
at the values of these variables, and conditionally compile different
code as appropriate for each library version.

No, I don't think GCC has a way to not include such files in the
dependencies.
