First question is, how does _XOPEN_SOURCE_EXTENDED affect your test
program?  I want to know first what the requirements are.

That seems like a sensible set of choices if your test program works. 
Perhaps the autoconf code doesn't do what we think it does.

Perhaps.  Or maybe he's *not* defining _XOPEN_SOURCE_EXTENDED when he
links his application, and the wrong library gets pulled in? 

As long as FreeTDS can be demonstrated to work correctly within a properly
configured environment, we can all go home and maybe leave a note
somewhere in the docs.  

It's getting late, no?  ;-)
