Hi,

Yes, normally I do this, but my cygwin.bat is (almost) virgin and does
not change PATH. There is actually no difference whether I run
cygwin.bat or start bash as bash -login -i from a NT command line
window as far as the PATH is concerned.

My cygwin.bat reads:
-----------
@echo off

d:
chdir \cygwin\bin
SET MAKE_MODE=unix

bash --login -i
-----------
No path mangling here. I just added the MAKE_MODE line to the
cygwin.bat shipped with the latest net release.

regards,
Markus
