That may not have been an altogether healthy idea.  autoconf-2.13 is
quite outdated.  OTOH, GCC source tarballs shouldn't need autoconf to
build, anyway, so that shouldn't really have hurt.

Are you sure you really should have used this --with-headers option?

Hmmm... that seems to contradict what you wrote further up (quote
moved down by me:)

This and the following ones appear to be the core of your problem:
*all* the places where it's looking for C++ includes are nonexistent,
it seems, leaving only C-only paths:

> /usr/local/compiler/cross/djgpp-2.04/lib/gcc-lib/i586-pc-msdosdjgpp/3.3/include
>  /usr/local/compiler/cross/djgpp-2.04/i586-pc-msdosdjgpp/sys-include
>  /usr/local/compiler/cross/djgpp-2.04/i586-pc-msdosdjgpp/include

This hints at an installation problem.  Do you have an <iostream> file
anywhere below /usr/local/compiler/cross/djgpp-2.04?

Certainly not the linker script --- you haven't come near the stage
where a linker script would be used, yet.  The problem is in the
definition of include directories used by the preprocessor.

Im quite sure they shouldn't --- the path they start in is an addition
to your --prefix, not an alternative.

That means something's gone seriously wrong.  C++ headers should never
be in there.
