[zeromq-dev] czmq fails on cygwin, mingw32, and mingw64

On Cygwin the configure script fails to link with C++ dependencies as
presumably due to static *libzmq*,

configure:12223: checking for zmq_init in -lzmq
configure:12248: gcc -std=gnu99 -o conftest.exe -I/tmp/build/include -g -O2
tmp/build/lib  conftest.c -lzmq  -lpthread  >&5
/tmp/build/lib/libzmq.a(libzmq_la-zmq.o): In function `zmq_init':
/tmp/libzmq/src/zmq.cpp:76: undefined reference to `___gxx_personality_sj0'
/tmp/libzmq/src/zmq.cpp:122: undefined reference to `std::nothrow'

gcc version 3.4.4 (cygming special, gdc 0.12, using dmd 0.125)

On Mingw64 either i686 or x64 fails as GCC hangs in the linker on *libzmq*.
 Compiler bug.

gcc version 4.4.3 (GCC)

On Mingw32 on MSYS there is a conflict on C99 *stdint*:

/bin/sh ../libtool --tag=CC   --mode=compile gcc -std=gnu99 -DHAVE_CONFIG_H
-I../include  -pedantic -Werror -Wall -Wno-unused -D_REENTRANT
