Yes, the makefile called "Makefile" is very Postgres-tree-specific. Not
intended to replace Makefile.unx or other ways of building a driver

OK, I'm not clear on the usage of odbc.ini. My odbc.ini looks like (note
that this includes my local mods for "Debug" and "CommLog"):

[ODBC Data Sources]
PostgreSQL = PostgreSQL Driver
Postgres = Postgres Simple Spec
PostgresODBC = PostgresODBC
Default = Postgres Stripped

Debug = 1
CommLog = 1
ReadOnly = 0
Driver = /opt/postgres/current/lib/
Servername = localhost
Username = tgl
Password = "no$way"
Port = 5432
Database = test


So, each database entry specifies the full information for each
database, including which driver to use, host info and account info.
What is the distinction between all of those entries and the "Debug" and
"CommLog" fields? What _should_ odbcinit.ini be providing which should
never be in odbc.ini?

So, I just finished removing the stubs and internal calls which I had
added in (having now found the linker options which make sure things
resolve within the library), when I found some additional stubs which
are in results.c. They have been there since before I touched the code.
Are they required for Windows? If so, why aren't the other routines
required to be stubbed as they were on my Unix box without the right
linker options??
