[DB-SIG] A small bugfix for sybase module

[Harri PASANEN]

ctsybasemodule.c

In line 31, where it fills up the description structure, some parenthesis are
in order.  After the fix the line looks like:

 ((fmt+i)->status & CS_CANBENULL) != 0); /* nulls ok  */


In the current release it is like

(fmt+i)->status & CS_CANBENULL != 0); /* nulls ok  */

Without the parenthesis at least  gcc 2.8.1 on Sparc-Solaris it seems as if it
is folding the constant CS_CANBENULL != 0 to 1 which then matches
the wrong status bit.
