OK, I finally took some time to look into this.  Martin, I think you 
work on the big merge looks very promising.

Yeah, I'd agree with that.  Also, the gmallocn function should make 
these ad hoc checks redundant, since the integer overflow check is now 
in the malloc function:

   if (pagesSize*(int)sizeof(Page *)/sizeof(Page *) != pagesSize ||
       pagesSize*(int)sizeof(Ref)/sizeof(Ref) != pagesSize) {
     error(-1, "Invalid 'pagesSize'");
     ok = gFalse;
     return;
   }

I don't know if 3.01 kills those checks, but lets get rid of them and 
commit the gmallocn patch for a start.

cheers,
Kristian
