I *knew* that I was going to get myself into trouble by responding with
more than "I dunno"...

I hope that you don't mind but I'm CC-ing pgsql-ports so others can
benefit from this too.

I just did the following (with 7.1rc4):

$ cd src/interfaces/odbc
$ make

The above produced psqlodbc.dll which seems to be exporting the "right
stuff." How do I test this -- I have never used ODBC before.

I'm quite willing to include ODBC support in my distribution. However I
will only include a Cygwin psqlodbc.dll -- including a straight Win32 one
is confusing and could cause some problems. There are too many Cygwin
to non-Cygwin interaction problems on the Cygwin mailing list already...

I just did the following (with 7.1rc4):

$ cd src/interfaces/odbc
$ nmake -f win32.mak

The above produced Win32 psqlodbc.dll and seems to be much easier than
trying to follow the steps in src/interfaces/odbc/readme.txt.

Anyway, if we can verify that Cygwin psqlodbc.dll works correctly, then
I will add the --with-odbc option when I configure from now on.
