# calling AC_PROG_CC or the like, since they will set a default
# set of CFLAGS ("-g -O2") if the user did not supply any, and
# we don't want those default flags to be carried over into the
# rest of the build system since we have other means of controlling
# debugging symbol generation and optimization.
