It's a minor inconvenience, so no worries.

But FWIW I regularly do this kind of build on Fedora.
gdb doesn't actually build there due to some gnulib bug,
but if you disable gdb+gdbserver you can build things by
configuring with --host=i686-w64-mingw32 and making sure
you have the right mingw* packages installed.

This can't happen in UTF-8, as all bytes in a multi-byte UTF-8 sequence
have the high bit set.

However it can happen in the 7-bit JIS encoding.  This isn't available on Linux
but maybe it is on Windows, I don't know.
