-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.
