Yes it should. The problem is in mingw gcc's (the gcc-2.95.3-20010608
vesrion that in in mingw-1.0).  It was built to use '/' as the primary
directory separator.  This works fine on NT and W2K, using cmd shell,
but not on W9x *or* when running gcc from tcsh, zsh, or as in your case
bash.

To fix your problem (I hope), download the gcc-2.95.3-20010613-W95patch
from SF and overwrite the gcc,c++, g++ ,f77 and cpp drivers in your
<mingw-root>/bin directory.  These updated binaries drivers were built
with a default dir separator of '\\'.  They work okay for me with
Cygwin's bash and with Amol's ports of zsh and tcsh (as well as with
the native cmd or command shell).
