Actually, there may be a simpler way than cmd /c start /wait
program_being_waited_for

/c/tmp> cat t
#!/bin/sh
date
/c/windows/notepad
date
/c/tmp> t
Mon Apr 19 09:51:35 EDT 2004
Mon Apr 19 09:51:47 EDT 2004
1 /c/tmp>

Ditto with #!/bin/bash.

So (at least on XP) if you just start the program without using cygstart or
putting it in the background with &, the shell just waits for it to finish.

Thanks! I've never run windows' shell from bash, but that does the
job.

I didn't try that: doesn't 'wait' just wait for the given period
(arg=n)? If so, that would be at best a kludge.
