No, gdb happens to be invariant because you don't have cross gdb
installed. You cannot debug 32bit code with 64bit gdb on Windows.

Cygwin gcc has never supported -m32.

Can you at least be specific about the errors? It is rather frustrating
reading your emails, being so vague about and all. Are you mixing Cygwin
and mingw code?

My advice is, stop jumping to conclusions, and stop assuming facts about
how things are related, and fix your email client to reply to threads
properly instead of starting a new thread for every reply.
