# ==== Purpose ====
#
# Check if the platform uses 64 bits for ulong.
#
# Note: Windows platforms can have 32 bit ulong even if the machine is
# 64 bit. So be sure to choose the correct condition for your test!
# Tests that check the range of system variables whose maximum is
# ULONG_MAX will depend on the ulong size, rather than the machin word
# size.
#
# ==== Usage ====
#
# --source include/check_64bit_ulong.inc
# # Now $have_64bit_ulong is 0 if ulong is 32 bits, and 1 if ulong is 64 bits.
