Re: experimental Unicode support

I'm attaching an updated patch. I haven't yet tested it on Windows, but
the fix is simple enough.

I have been unable to build psqlodbc satisfactorily with the PostgreSQL
config files, as the configure script fails to find support for shared
libraries. I did a quick test with a statically linked client.

When I stripped out the PGAC* macros and inlined PGAC_VAR_INT_TIMEZONE, I
was able to build and test a shared library. (I have not included those
changes.)
