file-has-acl: new module, split from acl And add a new module file-has-acl-tests to match. I ran into a problem with the recent changes to the acl module, as they introduced a typo 'test use_xattrs = 0' into 'configure'. When using the fixed version with Emacs, I discovered that file-has-acl wasn't separated out well enough for Emacs (e.g., it had multiple libraries, but needed only one), so I fixed that too. * NEWS: Document this incompatible change. * modules/file-has-acl, modules/file-has-acl-tests: New files. * m4/acl.m4 (gl_FUNC_ACL_ARG): New macro, split from gl_FUNC_ACL. Initialize gl_need_lib_has_acl. (gl_FUNC_ACL): Require it. Simplify use of 'test'. Set LIB_HAS_ACL if gl_need_lib_has_acl. Move the file-has-acl.c-relevant stuff to ... (gl_FILE_HAS_ACL): ... this new macro. Rewrite to fix 'test use_xattrs = 0' typo, and omit some needless work. Set gl_need_lib_has_acl=1 if we'll need LIB_HAS_ACL to be set when gl_FUNC_ACL is called. * modules/acl (Files, lib_SOURCES): Remove lib/file-has-acl.c. (Link): Remove $(LIB_HAS_ACL). * modules/acl-tests (Files, Depends-on, configure.ac, TESTS) (check_PROGRAMS): Move stuff relevant to file-has-acl to modules/file-has-acl-tests. (test_file_has_acl_LDADD): Move to modules/file-has-acl-tests.
