When odbc_autocommit function has only the connection id parameter, php crash with a
"core dump"!
<?php
$dbh = odbc_connect("localhost:ingoteam", "developer", "*********");
odbc_autocommit($dbh);
odbc_close($dbh);
?>
####### Your Problem!!! #######

#else
if (pv_onoff && (*pv_onoff)) {
#endif
###############################
When no DBMaker is activ (HAVE_DBMAKER does set), the
line "if ((*pv_onoff))" will not work! There was only
one option, pointer of "pv_onoff" is NULL, but the if-
statement check the value of "pv_onoff"!?
There are no way to check the autocommit status!
