FYI

This is a synopsis of changes to the 'current' Cygwin Postgres
source that are required to build PostGIS with the 'current'
Cygwin distribution

Note after applying the appropriate patches running the
included 'build.sh' script from the Postgres ROOT directory
*should* be all you need todo to build PostGIS

**BINGO **

With this change the DLL compiles and works !

What do we need todo to get this into the Postgres source ?

Many Thanks
