> when trying to build GCC 3.4.3 on an IBM IntelliStation 265 running AIX 5.2 > I get the following error message: This most likely is due to bootstrapping GCC on AIX 5.2 with GCC built for AIX 5.1. AIX 5.2 provides the atoll() function and GCC configuration finds it, but the AIX 5.1 "fixed" headers provided by GCC do not declare the function. To fix this, wipe out the "fixinclude" installed headers provided by GCC or add a declaration for the function. This will be fixed in the next GCC 3.4 release. David
