Actually, I suppose that setup should set the cygexec bit for /bin and /usr/bin.
It's been valid for a number of releases of cygwin.

The only problem is that mingw programs like strace.exe won't work correctly,
so they have to be "mounted" separately.

mount -f -b -x c:\cygwin\bin\strace.exe /bin/strace.exe
mount -f -b -x c:\cygwin\bin\strace.exe /usr/bin/strace.exe

Not too pretty...  Maybe we need another bin directory that holds non-cygwin
executables.  cygcheck.exe really shouldn't be a cygwin binary so it should
go there, too.
