ECPG and multiple threads

Hi,

I'm porting an embedded-SQL application to PostgreSQL so embedded sql
is a must for me. My application is multi-threaded. SQL queries are
used by several threads. The program keeps terminating unexpectedly in
deemingly "innocent" places.
I figured out that ecpg library can be responsible for this.
Here:
http://www.postgresql.org/docs/8.1/interactive/ecpg-process.html
I found the information that:
"The ecpg library is thread-safe if it is built using the
--enable-thread-safety command-line option to configure."
However my instance of PostgreSQL was installed from _binaries_ that I
downloaded from http://www.postgresql.org

The questions:
1. How do I know how my copy of libecpg.lib was built and if it is
thread-safe?
2. Is there a place I could get the thread-safe version of this
library if I don't want to get into building the whole stuff from the
source code?

Thanks in advance.

Adam.
