Right. But you don't have a choice in libgcrypt. There we demand that
the config.h as created by configure needs to there. It is a part of
the code. If you don't want that, you are on your own and then, if you
like, add @ifdef HAVE_CONFIG_H.

I am sorry, for you, but we use a different build system and as I have
said hundreds of times, building on Windows is not supported. A sed or awk
script to add the #ifdef HAVE_CONFIG_H si straightforward to implement
but in that case it would be easier to provide a condig.h (even if empty).

You are wrong. The ../src is required for VPATH builds. VPATH builds
are a Good Thing and actually required by the GNU standards and due to

It would clash with systems redefining msghdr using cpp tricks.

The semantics are different with your change.

Well, I want to use them. The directories are closely coupled and thus
it is better to express this with the file names.

This is a regression tests. By releasing the memory you change the test
and may not detect a regression. Okay, this is a bit of a theoretical
argument but I currently don't have the resources to fix and test the

These will be new tests.

As told, the ac funmctions will go anyway. They are seriously bugged.

No problem here to bootstrap it.

You are right. The configure tests are broken. Probably we never build
without some algorithms for a long time. I'll fix configure.

POSIX requires sys/un.h as it defines struct sockaddr_un. Windows is
irrelevant here. If you want to run change the build system for
Windows, I suggest to provide an sys/un.h stub.

First of all I am not sure whether this is the correct fix. We have
identified several inconsistencies in ac module and found no way to
properly solve that without an API change.
Second, yes bugs are to be fixed. But sometimes it is better not to fix
a bug if it would introduce a couple of new and unknown bugs. A
maintainer's job is to overview the overall stability of a software and
not to fix bugs just because there is a bug. In particular not if it is
in a part scheduled for removal.
Die Gedanken sind frei. Auschnahme regelt ein Bundeschgesetz.
