It's not acceptable? How then to invoke the bash itself :-)

It has nothing to do with my case. There is no globs, just plain file names.

Again, no relation.

Don't see yet how to do that.

Which feature? If Win32 paths are not handled properly inside bash, e.g.
bash-2.05$ bash -c "c:/cygwin/bin/ls.exe"
[ ... works ... ]
bash-2.05$ bash -c "c:\\\\cygwin\\\\bin\\\\ls.exe"
bash: c:\cygwin\bin\ls.exe: command not found
bash-2.05$
why do you call this "a feature"?

Not yet.
Hope to hear from you soon,
