Yutaka Tanida [yutaka@marin.or.jp] and I have examined IPC
library.
We found that postmaster doesn't call exec() after fork() since v6.4.
The value of static/extern variables which cygipc library holds may
be different from their initial values when postmaster fork()s child
backend processes.
I made the following patch for cygipc library on trial.
This patch was effective for Yutaka's test case.
Regards.
