The push for 8160873 touched a .m4 file in common/autoconf/ [1] but did not update the generated-configure.sh files. This was corrected in 8162409.

The check in make/Init.gmk (see below) did not fire. Need to investigate why and tighten up the check.


cat -n make/Init.gmk| less
 [...]
   138 # The spec files depend on the autoconf source code. This check makes sure
   139 # the configuration is up to date after changes to configure.
   140 CUSTOM_CONFIG_DIR ?= $(topdir)/closed/autoconf
   141
   142 $(SPECS): $(wildcard $(topdir)/common/autoconf/*) $(wildcard $(CUSTOM_CONFIG_DIR)/*)
   143 ifeq ($(CONF_CHECK), fail)
   144 @echo "Error: The configuration is not up to date for '$(lastword $(subst /, , $(dir $@)))'."
   145 $(call PrintConfCheckFailed)
   146 @exit 2
   147 else ifeq ($(CONF_CHECK), auto)
   148 @echo "Note: The configuration is not up to date for '$(lastword $(subst /, , $(dir $@)))'."
   149 @( cd $(topdir) && \
   150 $(MAKE) $(MFLAGS) $(MAKE_LOG_FLAGS) -r -R -f $(topdir)/make/Init.gmk \
   151 SPEC=$@ HAS_SPEC=true ACTUAL_TOPDIR=$(topdir) \
   152 reconfigure )
   153 else ifeq ($(CONF_CHECK), ignore)
   154 # Do nothing
   155 endif
