# The original 'makefile' has a flaw:
# 1) it overrides CFLAGS
# 2) it does not pass extra "FLAGS" to $(CC) that could come from environment
#
# It means :
# - we need to edit 'makefile' for different builds (DEBUG, etc...), which is
#   not practical at all.
# - Also, it does not allow to run all tests without editing the test source
#   code.
#
# To use this makefile (GNU make only):
#   "make": build with all predefined tests (without editing test source code)
#   "make mem": perform memcheck with all tests enabled
#   "make unit": build standalone (unit) test
#   "make debug": build standalone test with debugging code
#
# Original 'makefile' targets can be used (test, memcheck, clean, ...)
