<stddef.h> is required by C89, so yes, it was a redundant declaration. <stdbool.h> is not required by C89. However, nothing else in gnulib used the results of the test, and the idea is that if you are using gnulib's stdbool module, you don't care about a fully standards-compliant <stdbool.h>, rather you care about the subset of <stdbool.h> guaranteed by gnulib. So we trimmed the size of config.h for the sake of emacs: http://lists.gnu.org/archive/html/bug-gnulib/2011-01/msg00571.html -- Eric Blake ebl...@redhat.com +1-801-349-2682 Libvirt virtualization library http://libvirt.org
