# a) Fix build if limits.h provides definition for PAGE_SIZE, as musl does w/musl per XSI[1] although it's apparently optional [2].
# This value is only provided when it's known to be a constant, to avoid the need to discover the value dynamically.
# b) If not using system-provided (kernel headers, or libc headers, or something) use the POSIX approach of querying the value
# dynamically using sysconf(_SC_PAGE_SIZE) instead of hardcoded value that hopefully is correct.
