* lib/am/install.am (install, install-exec, install-data, uninstall): Declare conditionally using a if/else/endif block instead of using ?SUBDIRS?-style conditions. The latter fail when %maybe_BUILT_SOURCES% is replaced by several lines. This fixes a bug introduced on 2003-04-06. * tests/bsource.test: New file. * tests/Makefile.am (TESTS): Add bsource.test.
