Seems to be a bug in the debugging info (gcc is probably not very
COFF-oriented).  Try changing the -g in the compiler flags to -gstabs
(or -gstabs+3 to have huge amounts of debug info); that might help.
I'd also suggest submitting a PR about this at the GCC GNATS page.

Those are probably due to the -B option used and are harmless (I hope).

Unless I'm mistaken, this resolves to

  /opt/djgpp/i586-pc-msdosdjgpp/include

Are you sure you extracted djcrx203 into /opt/djgpp/i586-pc-msdosdjgpp?
