You don't seem to understand what's going on... On MSYS there
is no official way to convert a posix path to a win32 path

outside of the MSYS /bin or /usr/bin directories (and perhaps
other places as well?), any argument that looks like a posix
path is converted to a win32 path on the assumption that all
such executables expect win32 paths. The problem is that in
this case the conversion needs to be done not on an argument,
but on an environment variable that MSYS does not autoconvert.
So, it needs to be converted manually. So, since there is no
official way to convert paths, I run a program outside of MSYS
and as one of its arguments I have the posix path to be
converted. The program I have chosen to run is the command
This is the script I run under MSYS or Cygwin to convert a POSIX path
to a win32 paths with varying amount of escaping in case the result
needs to be handled by a script later. It has been pointed out to me
that Windows converts forward slashes to backslashes so it is not
necessary to generate backslashes, but paths are often seen by Windows
users so I try to generate paths which are familiar to them.
