Re: Patch for the getpagesize module

Hello Martin,

Thanks for your patch.

Yes, I agree this is useful, because although POSIX does not specify
getpagesize() any more, SUSV2 had it declared in <unistd.h> [1].

What is the point of doing that? A function that in most cases just returns
a fixed number can well be inlined. And since 'inline' is a bit tricky to
use portably, we chose to implement it as a macro. What drawbacks do you see
with that?
