Custom types for a Windows server

Hi there,

we made some custom types (written in C) for PostgreSQL onto a Linux
server.
We need to deploy a Windows server...

The documentation does not talk about a shared library for Windows
(http://www.postgresql.org/docs/8.1/interactive/xfunc-c.html#DFUNC)
I tried to compile its custom types with borland bcc32, with no success:

Does somebody can help me ?

Thanks

Armel (who writes English very bad...)
