No, nor 1.5.19.

1.5.19 broke several things with respect to our application like: needing
to sync the Windows environment with the Cygwin one due to a use of
CreateProcess, needing to increase the scheduler resolution via
timeBeginPeriod back to 1 ms, dealing with the .exe that is now appended
to the /proc/self/exe symbolic link, etc.

These were all our issues; not Cygwin ones.  There was one Cygwin
one with clock_[get|set]res that affected nanosleep in 1.5.19, but I
submitted a patch for that and it is now included in 1.5.20.

The point is, I've just gotten around to fixing all these known problems
in our application and retesting.  So please, no one complain that I
didn't report it sooner.

* Brian mumbles about all the qualifications that one was coming soon when
time permitted that were trying to avoid Corinna's mumbling above.  Brian
also mumbles that the attached STC is nothing more than wrapping the
code fragment quoted in the previous message with a main, setting the
variables as the comments indicated, and manually stripping out the
preprocessor conditionals. *

STC attached.

(Why is it that no matter how hard I try to avoid objections to my emails
I ALWAYS get them anyway?  I know, WJM.  I just tend to agree with others
that this doesn't foster any good will in the Cygwin community.  Yeah, I
know, TITTTL, but I don't read that list.)
