I didn't know that you could coalesce macros like that.  What a
strange thing to do while not allowing values to be assigned.

Yup.  It would be really good if there was a way around that
abomination but the FreeTDS people do not put their version identifier
in any useful format that can be used by the C preprocessor.

Applied.  Thanks for that.
