(msys building is buggy, please be aware, it fails to compile on my
machine) also I modified the buildall.bat/buildbase.bat to use correct
MSVC versions instead of "visual studio 2017"
Solution: even though epoll() semantics are supported in modern illumos, it may differ from what Linux developers are used to expect. Skip epoll and use poll or select semantics (both were checked to work well).
Solution: keep the new --without-docs option, but also keep the old
--without-documentation with an added deprecation warning.
We can then remove it in the next major release, to leave enough time
for users and maintainers to change it without disruptions.
It's especially annoying to see this:
--enable-perf Build performance measurement tools [default=yes].
--disable-eventfd disable eventfd [default=no]
--enable-curve-keygen Build curve key-generation tool [default=yes].
Solution: all options should explain the non-default case. Also
the language should be enable/disable, with/without, rather than
yes/no. E.g. '--without-docs'.
Specifically, the poller detection code does not set macros in
platform.hpp. The configure script passed them as -D on the command
line.
Solution: rewrite the poller detection code.
Specifically when cross-compiling, one can be willing to force these
variable values using the environment of a config.cache file. This
commit makes this possible.
The affected variables are:
* libzmq_cv_sock_cloexec
* libzmq_cv_so_keepalive
* libzmq_cv_tcp_keepcnt
* libzmq_cv_tcp_keepidle
* libzmq_cv_tcp_keepintvl
* libzmq_cv_tcp_keepalive

The decision about the poller mechanism to use (select, poll, ...)
was done twice: once by the build system and once by the code in
poller.hpp. As the build-system can actually detect the mechanisms
available, prefer that result to the hard coded defaults in
poller.hpp.
At the same time, remove the duplicate detection of select() vs.
poll()-variant from proxy.cpp, signaler.cpp and zmq.cpp.
This patch has not been tested on many build platforms: especially
the cmake build needs testing / patching. For the other builds,
hard code the result as these these are all Windows platforms.
- Added a macro for checking clang compiler
- Moved basic compiler checks to a macro
- Added a macro for checking if compiler supports a flag
- Added --enable-debug flag
- Added a macro for running normal autoconf check with compiler flags
- Added a macro for checking for verbose flag for different compilers (-Wall)
- Added a macro for turning on strict standards compliance
- Added a macro for turning warnings to errors
- Added a macro for checking if compiler supports given pragma
- Most of the flags now go through checks if the compilers supports them
rather than enumerating different compilers
- Added DSO symbol visibility for sun compiler
- Enabled verbose mode for sun compiler
- Fixed build for ICC 12.x by adding -wd279 to size_t checks
- Removed pkg-config checks as those don't seem to be used anywhere

The patch tests that the C and C++ compilers actually exist
and work. autoconf seems to default to 'g++' when C++ compiler is not
found, which causes the following error (when the compiler isn't
there):
checking for uuid_generate in -luuid... no
configure: error: cannot link with -luuid, install uuid-dev.
The config.log contains the real error message "g++ command not found"
but the error message shown to the user is misleading.

I ran autoupdate on the configure.in, which generated most of the
patch attached. There is also a small manual fix in which removes the
warning "Remember to add LT_INIT to configure.in" which I assume is
because AC_PROG_LIBTOOL was called inside a macro.

Allows building without documentation even if asciidoc and xmlto are
installed. This eases up working with the build system because doc
generation take quite a while on repeated builds.

After long discussions in IRC we came to conclusion that there is no
elegant way to handle static builds with MinGW32. This patch sets
AC_DISABLE_STATIC by default on MinGW32 and Cygwin
