configure: misc updates
This patch removes the following macros: * AC_PREREQ checks for 2.61, which is not supported any contemporary distribution. * AC_COPYRIGHT, autoconf documentation states "in addition to the Free Software Foundation's copyright on the Autoconf macros, parts of your configure are covered by the copyright-notice.". This only refers to the autoconf infrastructure: we are doing simple and standard usage of autoconf infrastructure, we also don't use this macro in other existing userspace software available at The comment above at the beginning of this file shows text that is available in many templates on the Internet. * AC_CANONICAL_HOST, we don't need the canonical host-system type to build this software. * AC_CONFIG_SRCDIR is not used in other userspace software in the tree. * AC_DEFINE _GNU_SOURCE, define this where it's needed instead. * AC_DEFINE _STDC_FORMAT_MACROS is not used in this codebase. * AC_HEADER_STDC checks for ANSI C89 headers, however, we need more than just this C standard, so this doesn't guarantee anything at all. * Remove "Checks for libraries" comment, it's obvious. * AC_HEADER_ASSERT allows us to disable assertions, this is bad because this is helping us to diagnose bugs and incomplete features. * AC_CHECK_HEADERS is checking for an arbitrary list of headers, this still doesn't even guarantee that we can actually do a successful compilation in a broken system.
