This is a bit confusing... on some architectures, PAGE_SIZE is 
undefined, because it's variable.  To get the page size, one has to do 
getpagesize(), but it's not even clear to me that that is the right thing.

I've applied the patch, but could you perhaps try to find out how this 
is supposed to work on architectures where page size is variable?
