Description:
------------
Got me the latest Stable version of 4.3 off snaps.php.net.
Configure went smoothly (except for one warning that bison 1.28 is needed, we have 1.25).
The very first compilation, however, fails with below messages :

Stop.


Does this ring a bell anywhere ?

Your help much appreciated.
