What sort of precompiler are you using for the embedded SQL?  I can't  
remember Sybase ever having that but it may just be a product we never  
bought.  That's one component I don't know of a replacement for (not  
saying there isn't one, just that I don't know of it).  Depending on  
what the precompiled code looks like, you could end up in a situation  
where you can compile the .cobpre (or whatever it's called) but not  
the .cob.

As the other Craig said, you won't necessarily have binary  
compatibility, but you should have source compatibility as far as  
libsybdb goes.  It's possible there could be some routines you're  
using that are unimplemented in FreeTDS; you'll just have to try it  
and see.  I've never made the FreeTDS build produce shareable images,  
so if you'd been using those, you'll have to switch to static linking  
or modify the build.

Right, since 1998 or so.
