-- FreeBSD compatibility: fix invalid preprocessor directive '#ifdef __APPLE__ || defined(__FreeBSD__)'
-- (the '|| defined(...)' part is silently ignored by the preprocessor). The correct form is
-- '#if defined(__APPLE__) || defined(__FreeBSD__)'.
-- Also adds FreeBSD-specific memory query using sysctl(3) instead of sysconf(3), as
-- _SC_AVPHYS_PAGES is not available on FreeBSD.
