Description Johannes Waldmann 2008-10-27 00:35:39 CET

Ausdruck  (true || false == false)    bedeutet

in Java:  true || (false == false)
autotool: (true || false) == false

nicht so schlimm, da man immer den autotool-Formelbaum sieht,
aber doch eventuell verwirrend.

Die Präzedenz der Vergleichsoperatoren (==, ..) hier 
sollte höher sein bzw. die von UND und ODER geringer:
