OK, great.  I am surprised it worked the first time.  I didn't test it
here, and I am know more for my persistance than skill.  :-)

I have applied the rest of the patch.  It adds a check to the
backend/libpq Makefile and aborts if the two C md5.c files are not
identical.

There are two copies of md5.c because odbc has to be compile-able on its
own, and md5.c is also used by the backend and libpq.  With this check,
the two files will remain in sync because it will not even compile if
they aren't.

Also, odbc/md5.h has copies of certain definitions that normally appear
in include/c.h.  Because md5.c must compile alone in the odbc directory,
I needed those defines pulled out and added into odbc.  I will document
that these defines also appear in odbc/md5.h.
