Thanks to everyone for the responses, I haven't had a chance to try the
threadsafe version.
But I have tested for "man asprintf" and "man vasprintf" both returned
not found or something to that effect.  I did the grep as well nothing
turned up.  I'll try to
look into it some more tomorrow.  Thanks.

later

Hi!  Thanks for the PR.

Yes.  OS X perhaps has another variation on the theme for SC_PAGESIZE?
What do you get for the following:

$ grep -r SC_PAGESIZE /usr/include
/usr/include/sys/unistd.h:#define       _SC_PAGESIZE            28
/usr/include/sys/unistd.h:#define       _SC_PAGE_SIZE
_SC_PAGESIZE

More interesting, what says "man asprintf" and "man vasprintf"?  Are they
not implemented by Darwin?  The FreeTDS asprintf.c module should not come
into play unless the OS does not provide these functions.

I would be happy to fix FreeTDS to accomodate OS X, if we can find the
equivalent of SC_PAGESIZE or correctly assess the presence of vasprintf(3).


In the meanwhile, you can patch src/tds/asprintf.c as follows:

On line 41, you'll see:

           #ifdef _REENTRANT

change that to:

           #if 1  /* always very true */

and rebuild.  This change will force use of a slower (and threadsafe)
version of asprintf(), without invoking other threadsafe functions.

But I would like to fix your build properly.
