+dnl CF_ENABLE_PC_FILES version: 3 updated: 2011/07/16 20:37:23
+dnl ------------------
+dnl This is the "--enable-pc-files" option, which is available if there is a
+dnl pkg-config configuration on the local machine.
+dnl
+dnl It sets/updates PKG_CONFIG_LIBDIR, which is used by pkg-config as a
+dnl special case: overriding PKG_CONFIG_PATH (preferred).
