PATH for Cygwin isn't a problem.  Cygwin adjusts the PATH to be POSIX
compliant even if executed from the DOS shells. 
PATH will be a problem for MinGW if Amol's ZSH port is used for the
Bourne compatible shell.  The multipath separator will then need to be a

If we introduce some other shell, for which I haven't even tried, there
may be problems with even finding the PATH variable as Win32 usually
names it Path and environment variables are case sensitive.  Amol, in
his ZSH port, ensures that the variable is named PATH; however, other
shell ports may not be so wise.
