+dnl Function to configure a sub-library now, because we need to know the result
+dnl of the configuration now in order to take decisions.
+dnl We don't worry about whether the configuration worked or not - it is
+dnl assumed that the next thing after this will be a package-specific check to
+dnl see if the package is actually available. (Hint: use pkg-config and
+dnl -uninstalled.pc files if available).
+dnl code based on a simplification of _AC_OUTPUT_SUBDIRS in
+dnl /usr/share/autoconf/autoconf/status.m4 which implements part of
+dnl AC_CONFIG_SUBDIRS
