Grrr :-(

Not really.

Hm, I think the only info would be what this code.. does for your cygwin 
install...

     char cygpath[256];
     cygwin_conv_to_posix_path("c:\\foo\\bar", cygpath);

The key info is the value of "cygpath". The above is part of the 
var_expand_unit_test function in expand.c. So perhaps you can run the 
jam0.exe in GDB, set a break point at the above point, and see what happens.

Unfortunately the docs on cygwin_conv_to_posix_path are rather slim 
<http://www.cygwin.com/cygwin-api/func-cygwin-conv-to-posix-path.html> 
so using it is a hit and miss effort.
