18 # The toplevel makefile overrides $(CC) (in EXTRA_HOST_FLAGS) by setting
19 # it to whatever CC was in the toplevel configure. This breaks in Gnulib with
20 # older GCCs, because Gnulib's configure uses this variable to store the
21 # standard-setting switch (e.g. -std=gnu99/-std=gnu11). To fix this, we just
22 # set MAKEOVERRIDES to empty here so that import/ uses the right $(CC).
24 # This problem is visible with compilers that don't use C99 by default, such
25 # as GCC 4.8.5 (Centos 7).
