I'm not sure what you are implying. unless getpagesize returns 1, the
behaviour for gcc will be consistent for all larger sizes. If it's 4k,
then a file that is 4k will behave the same way as a 64K file if the
pagesize returned is 64k.
You seem to be implying that something bad happens when the file size ==
the returned page size.
What is that bad thing?
