These are almost certainly wrong. You can't use any of the stuff found
in the _native_ include directories /usr/include and
/usr/local/include for a _cross_ compilation.

This cannot possibly be right. You can't use your Linux libstdc++ for
cross-linking (and even of an incompatible version level wrt your
cross GCC). You'll have to install a cross version of libstdc++,
either from a full cross-build of GCC and libstdc++ sources, or from
the gpp281b.zip DJGPP distribution file.
