This never works, even in any other directory. It's the same problem
which disallows checkX to work, as reported in
The cause is an optimization when calling cygwin executables. So far,
Cygwin executables got their arguments via mmeory copy as well as via
the single-line cmdline argument of CreateProcess. We removed the
latter since it was never meant to work that way in the first place.
Unfortunately it turns out that run/run2/checkX are Cygwin executables
which don't have a main routine, but rather a WinMain routine. The
latter has a single cmdline argument, which is generated via
GetCommandLine(). But since Cygwin executables get no single-line
command line anymore, this stopped working.
