Thanks Igor.  I've downloaded the cygwin cvs and am trying to track down
what's up in any spare time that I get.  In the meantime though, I've copied
some code from a testcase for one of the patches and made some of my own
modifications to run it using inetd.  With 1.3.20, the code is ok.  With
1.3.22 however, the calls to fgets(), fputs(), and fflush() all fail with
"Socket operation on non-socket" (errno=ENOTSOCK)
