I understand. So better/feasible would be:

Windows: Check <gdb executable>/../lib/python27 or any configure-time
specified relative path to gdb executable? If that fails, revert to
current behavoir.

POSIX (so pretty much everythin else): Keep current behavior.

Which would come down to a configure option+ a small block of #if
_WIN32 code in the Python part of the code.

Thanks,

Ruben
