Doesn't build on musl systems

the following patch fixes this:

Excuse my ignorance. What's a musl system?

If there is a conflict between our global variable PAGE_SIZE and a macro defined in a header file, it may be cleaner to rename our variable to something like g_page_size.

musl is an alternative to glibc: https://musl.libc.org/

I don't know much about C and especially not these kind of global variables, that's why I made this an issue instead of PR.

Some more info about PAGE_SIZE in musl:

Do you perhaps have a fix for 5.6?

Unfortunately I am getting errors on my system

PAGE_SIZE is a reserved symbolic name of <limits.h>[1], so it is not an issue that can be fixed on musl side.

There is an open bug in Gentoo[2] on ROCT-Thunk-Interface (one of multiple).
