If you're going to do this *please* do PAGE_SIZE at the same time. It suffers
from the same problem on architectures where that's variable (m68k being
the only one I know of - 8K for sun3, 4K for other things) Right now you
need two libc's to solve this problem.
Then explain how one 32-bit glibc handles both 4k and 8k page sizes on
sparc64 systems. The get_pagesize() system call makes this work.
I do agree however that all of these sort of items should be unified
into one sysconf() interface. We were just lucky on Sparc and
inherited the system call from SunOS etc.
