hi
when launching cygwin's programs from within windows's cmd
if the command line parameter has two backslashes and is double quoted (e.g. a
path to local network drive)
then inside cygwin's program the corresponding ARGV element has single
backslash only
but without double quotes all is ok - both backslashes are kept
simple testcase

This probably means that Tcl wasn't installed properly.
