Assuming the AC_CONFIG_SUBDIRS enhancement is made, "compile-if-you-have-a-C++-compiler" should be implemented in terms of it, by putting the C++ code in a subpackage. This will avoid a lot of rarely-used "[action-if-succeeds], [action-if-fails]" goo spreading throughout the API. IMHO, adding such goo to AC_CONFIG_SUBDIRS is justified precisely because using subdirectories is a common and obvious way to factor out optional subcomponents of a package. It's a single change that's sufficient to handle a wide set of similar cases. -- | | /\ |-_|/ > Eric Siegerman, Toronto, Ont.
