Solution: use libbsd by default when available, and the internal implementation
only as a fallback, to take advantage of Linux distros maintenance of the
string libraries.
Allow "configure --disable-maintainer-mode" to disable timestamp checking.
This is useful for one-off builds, in particular on e.g. clusters, where slightly skew clocks force aclocal and friends to kick in for no good reason.
Solution: detect cacheline size for aligment purposes at build time
instead of hard-coding it, so that PPC and S390 can align to a value
greater than the 64 bytes default.
Uses libc getconf program, and falls back to the previous value of 64
if not found.
Solution: use requires.private, which pkg-config expands recursively
so that dependencies of dependencies can be linked against when
using pkg-config --static
Solution: go back to using -Wl,--version-script.
Use ax_check_vscript.m4 from the autoconf-archive to detect support on
multiple platforms (eg Solaris ld(1) -M).
libtool -export-symbols-regexp used ld(1) --retain-symbols-file under
the hood, the latter lets some C++ weak symbols make their way into the
dynamic symbols table, along with the zmq_* interface. The reason for
such behavior is unknown to me.
Solution: if the compiler supports it, pass C++98-compat flags.
Currently Clang supports this flag but GCC does not.
Add a new flag to enable it, as building with C++98-compat but also
with -std=gnu++11 will cause a lot of warnings due to the backward
compat ifdefs.
Add a CI job to run it and ensure we don't break compatibility.
Solution: ignore tautological-constant-compare warnings, as they
might be useless on 64 bit but they are not on 32 bit where sizeof
size_t != sizeof uint64_t
The original configure.ac tries to check for dladdr, but it actually needs
it only in case we have libunwind (which has a another section and checks for it
too).
This can fail the build on systems without dynamic linking support.
Therefore, the dladdr check has to be preformed only when checking libunwind.

Solution: revert the revert!
Revert "Problem: regression in 4.2.3 went unnoticed, want to release 4.2.5"
This reverts commit 5f17e26fa4c60c3de0282d1b6ad1e8b7037ed57a.
Solution: revert DRAFT -> STABLE API transition so that we can do a
bugfix-only 4.2.5 release.
Will be re-reverted once tagged.
Revert "Problem: ZMQ_BINDTODEVICE has met STABLE conditions"
This reverts commit 3cb79f5042cf32cdb7b1b58d4acf17eba85ec9f7.
Revert "Problem: ZMQ_MSG_GSSAPI_* have met STABLE conditions"
This reverts commit 374da4207b8034b0fcd67a2cc2165d50e09b9387.
Revert "Problem: ZMQ_MSG_T_SIZE has met STABLE conditions"
This reverts commit 6411c4a247c08ead50919d16b30eb030eaf44a7e.
Revert "Problem: docs say STABLE API still in DRAFT"
This reverts commit 9f2f30b7ffa09acc51d3b87251a47e83b435d5d4.
Solution: move it from DRAFT to STABLE since it's been in a public
release, committed for 6+ months and has not changed.
Given a new STABLE symbol has been added, bump minor version number.
* Problem: TIPC availability check is too strict
Solution: at build time only check if the API is available. In the tests
do a first check and a skip if the functionality is not available.
TIPC needs an in-tree but not loaded by default kernel module, tipc.ko
to be loaded, which requires root, so it is unlikely to be available on
any build system by default.
This will allow most distributions to ship with TIPC support built in,
and to avoid tests failure if the module is not there.
* Problem: no Travis tests for TIPC
Solution: mark one job with sudo: required and load the kernel module
* Problem: CMake fails when test returns 77 (skip)
Solution: set property to let it mark the test as skipped as intended
