Sorry, I should explain more

exec("C:/cygwin/usr/local/program.exe") fails
exec("C:\\cygwin\usr\local\program.exe") works (\\ c-style escaped)

and program.exe receives the first format from start|run, and from
shortcuts, or double-clicking on a program. So having a program that calls
exec based in it's own path will need an library call equivalent to
cygpath -u (which looks to be cygwin_conv_to_posix_path(name,
convertedname), or for argv[0] to be a little more consistent.

I've put cygwin_conv_to_posix_path in the program I'm working on, All i'm
saying is that a longer term solution might be to put something in the
startup code..
