I'm going to submit another version to review this week-end. A few problems 
with current implementation:

* it calls check_include_files() which tries to compile a C (not C++) 
binary; this fails if acl.h contains a c++-style comment (i.e., if acl is 
not patched by distro).

* No documentation for HAVE_*

* Should set ACL_INCLUDE_DIRS, ATTR_INCLUDE_DIRS to $acl_prefix/include;
$attr_prefix/include.

* No documentation for ATTR_LIBS.
