plPGsql and PostgreSQL 7.1beta4 in Cygwin doesn't work

Hello.

I've installed cygwin 1.1.8, with the latest snapshot with mmap corrections,
installed cygipc, compiled PostgreSQL 7.1beta4. Made the regression test
using make SHELL=/bin/bash check, ant it passed all 76 tests.

Then I created a database for productions with initdb, created some tables,
and tried a plpgsql function. It hangs the server everytime. Even a very
small plpgsql function hangs. Tried createlang with the -L parameter, and it
gives the same problem. The same plpgsql function works great on the Linux
PostgreSQL.

Anybody have clues? Could it be related to cygwin 1.1.8?

Thank's,

Eduardo Stern
