# General compilation flags.  "OPT" and "DEBUG" intentionally have
# short names so that it's easy for a user to override them from the
# command line.  CXX_OPT_FLAGS, CXX_OPT_SIZE_FLAGS, CXX_MACH_FLAGS,
# and CXX_EXTRA_OPT_FLAGS are set by configure.
#

# Set the default compiler options from OPT and DEBUG.  If the user
# wants to change the optimization or debug settings, he should set
# one of those on the make command line.  CXX_STD_FLAGS,
# CXX_CHECK_FLAGS, CXX_THREAD_FLAGS, and EXTRA_COMPILE_FLAGS are set
# by configure.
#
# [Note that using CXX_CHECK_FLAGS in AM_CFLAGS, which is used by the
# C compiler, is a little hacky, but usually works in practice as the
# C and C++ compilers are usually the "same" compiler and so accept
# mostly the same options.  If this turns out not to work for some
# compiler, a separate "C_CHECK_FLAGS" variable could be introduced
# which contains check options specifically for the C compiler.]

# options:  later options always override earlier ones, even if the
# earlier one was more specific).
