Hi james,

The ./configure script that you generated
(http://www.schemamania.org/projects/freetds/configure )
ran fine in my QNX machine and detected sys/select.h:

# ./configure | grep -e select
checking sys/select.h usability... yes
checking sys/select.h presence... yes
checking for sys/select.h... yes

but I can't see a #define HAVE_SELECT_H 1 in include/config.h.

It also detected both _vbprintf() and _bprintf functions OK (the same issue
in the config.h file).

(I cannot see the patch that I sent in the Nightly Snapshot, but I do see it
if I browse the CVS copy via WWW).

ANOTHER ISSUE===================================
When trying to compile the latest Nightly Snapshot available I also get a
new error:

It seems that src/replacements/iconv.h was recently re written (yes, I known
it for sure, since I read related messages), and one of the new lines uses
the EILSEQ errno value (line 203).

The problem is that QNX4 errno.h doesn't have that definition (EILSEQ).
What about a:

#if defined (__QNX__) && !defined(EILSEQ)
#define EILSEQ EINVAL
#endif
in include/tds_sysdep_private.h

and a

#include "tds_sysdep_private.h"
in src/replacements/iconv.h

?

Understood.  That's why my tests are formed the way they are:

> #if defined (__QNX__) 
> # if !HAVE_VSNPRINTF && HAVE__VBPRINTF
> #  define vsnprintf _vbprintf

Disregarding the compiler, we substitute _vbprintf for vsnprintf only if
we have one and not the other (and only for QNX).  I'm testing directly
for the existence of the functions; you're using the compiler as a proxy
for the version of QNX.  It's not impossible that Watcom will reënter the
market, or that someone using Watcom would have added vsnprintf(3).

Thank you for going to the trouble.  Your patch applied perfectly.

Not at all.  I learn portability through vicarious experience.  (!)

Use it in good health.
