'emacs' command becomes a no-op

[Chap Harrison]

After bringing everything up-to-date in Cygwin (Windows Server 2003),  
emacs won't run.  I give the command, it thinks for half a second, and  
then gives me the command prompt.

I'm also noticing different behavior from readline in a Perl script.

I'm using mintty, which got upgraded in the process.

If there's a system log somewhere, I don't know where it is, to look  
for error messages.

Could anyone suggest a next step?

Thanks,
Chap
