If automake has the ability to flatten the += syntax so that non-portable make advances can be used, why can't the same logic apply to wildcard usage? The biggest argument against it that I've heard is that it is a GNU-only option. However, I've suggested in the past that it'd be great if Automake can just process the wildcard and output the Makefile.in accordingly. It sounds like my suggestion wasn't that wild afterall if Automake can do this currently for things like +=. When you have a library with 357 source files, the list in Makefile.am becomes unwieldy.
