Also correct the comments. Thanks. I removed the comment about jc1 (Java was removed a while ago) and installed the rest of your patch onto the trunk. Jeff

When doing 64-bit builds of GCC on AIX, genautomata experiences malloc() failures. It seems that a 512MB heap is no longer big enough. I also updated the comments in this file to match the values passed to the linker. The AIX `ld` manual says this about the maxdata option: Sets the maximum size (in bytes) that is allowed for the user data area (or user heap) when the executable program is run. So the comments were giving incorrect values. gcc/ * config/rs6000/x-aix: Increase memory limit for genautomata on AIX. It has been experiencing malloc() failures during 64-bit compiler builds. Also correct the comments.
