------- Comment #22 from paolo dot carlini at oracle dot com 2010-01-10 12:16 ------- I don't know what you mean exactly by "official", but certainly disabling the build of the PCHs cannot hurt and cannot create any problem, beside the testsuite running slower. Then, if you actually use PCHs in your own work you can of course try to build them at a later time.
