Today I was looking around for a bug in autoconf, and I noticed one interesting bit out of the NEWS file of the current git version:

Present But Cannot Be Compiled: Autoconf will now proceed with the compiler’s result if a header is present but cannot be compiled. The warning is still printed, and you should really fix it by providing a fourth parameter to AC_CHECK_HEADER/AC_CHECK_HEADERS.

This is a tremendously useful thing to know before autoconf 2.64 is released, which is hopefully not too soon. The reason for this is that finally, after years of having that as a warning, to the point that some projects even ignored it altogether, the new autoconf will start ignoring header files that cannot be compiled, for whatever reason. This is useful since it ensures that headers are not detected that lacks proper dependencies. Unfortunately this also means that any software that currently relies on header files found without compilation will change behaviour.

    It's been five almost five months since the developers behind the Debian-based Devuan GNU/Linux operating system launched the second Beta version towards the first stable release of the OS, and they now announced the Release Candidate. The Devuan project continues its vision of providing a libre Debian fork without using the systemd init system, and the Release Candidate (RC) version brings the GNU/Linux distribution closer to a final release. The interesting fact is that this RC appears to be stable enough to be used for production work.
