my_getpagesize(): New function; returns the size of a page of memory.

Browse source 
Versions are defined for Windows and Unix; the Unix
                   flavor uses sysconf() to get the page size; this avoids
                   the use of getpagesize(), which is deprecated and
                   requires an additional library on some platforms
                   (specifically, Reliant UNIX).

This partially closes SourceForge bug #113797.
