It understand that on Windows a full installation will now provide two DLLs,
psqlodbca and psqlodbcw. With the Unix builds, we're still at the old scheme
of having a single psqlodbc library which can be built in one of two ways.
For binary packagers, this seems quite impractical. It seems best to change
to the -a and -w names as well, depending on which way you configured. (When
builidng a binary package, you just run the build process twice.) The only
slight concern about that would be that this breaks existing odbcinst.ini
files. Maybe one could discuss whether the -a or the -w variant provides the
most faithful backward compatibility, but I tend to think that users are
perhaps better served if they are forced to stop and decide with which
variant they want to proceed. Ideas?
