-# jconfig.h is the file we use, but we have another before that to
-# fool autoheader. the reason is that we include this header in our
-# API headers, which can screw things up for users of the lib.
-# jconfig.h is a minimal version that allows this package to be built
+# NOTE: autoheader automatically modifies the input file of the first
+# invocation of AC_CONFIG_HEADERS, so we put config.h first to prevent
+# jconfig.h.in from being clobbered. config.h is used only internally, whereas
+# jconfig.h contains macros that are relevant to external programs (macros that
+# specify which features were built into the library.)
