Hi, Pablo.  Let's see if we can help you.

I added detection for sys/select.h to configure.in (generates
./configure).  That should automatically notice the file.  It will be in
tomorrow's snapshot.  Please post a patch with:

#if HAVE_SELECT_H
# include <sys/select.h>
#endif /* HAVE_SELECT_H */

in the appropriate files.

These are very nonstandard functions.  I suppose the least intrusive
approach is to add something like this to include/tds_sysdep_private.h:

#if defined (__QNX__)
# define vsnprintf _vbprintf
# define  snprintf  _bprintf
#endif /* QNX */

If you do that and it works, please send us the patch, and I'll apply it.
