Note that, (1) both library libws2_32.a check report `no', and (2) the compiler is exactly my simulation target `gcc'.
I know that I can add a check into configure.ac to examine whether building in mingw or cygwin, but is this checking supposed to be fully examination for the real build environment ? If it works fine, LIB variable should be full filled with all required library link options. If there a simple way by adjust my MSYS+MinGW environment to make autoconf works, please tell me.
Look in the generated config.log for the errors produced while testing
for WSAGetLastError. The errors may provide a clue as to what has
actually gone wrong and lead to fixing the problem. Autoconf tests
for library functions by linking a small test program. Sometimes it
is necessary to supply additional libraries in order to successfully
link with a library.
