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