General issue

Linking with libc.a can be especially problematic.

However, if you have a dxe written in c++, and especially if your
exe is C-only, linking dxe with libstdc++ is a good thing

As for duplication of symbols: Well that's a known general issue
because djgpp libc is a static library.

You should run dxe3res against a dxe module, not an archive,
like: dxe3gen -o tmp.c my.dxe

As for rest of your notes, I will try looking at them later.
