For very high-speed message systems, the memory used for recovery can get to
be very large. The corrent limitation on that reduction is the ZMQ_RECOVERY_IVL
of 1 sec. I added in an additional option ZMQ_RECOVERY_IVL_MSEC, which is the
Recovery Interval in milliseconds. If used, this will override the previous
one, and allow you to set a sub-second recovery interval. If not set, the
default behavior is to use ZMQ_RECOVERY_IVL.

On systems using GCC 4.0 or newer which support symbol visibility in shared
libraries, use -fvisibility=hidden and only export explict API functions
defined in zmq.cpp. We do not enable -fvisibility on MinGW since this uses a
separate mechanism (__declspec).

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.

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
Signed-off-by: Mikko Koppanen <mkoppanen@php.net>

MinGW32 defines __int64_t as long long, which causes the build to fail
unless -Wno-long-long is used. In addition the shutdown_stress test
isn't currently compatible with Win.
