 For Windows build, please follow this note :
	1) install package gcc-multilib gcc-mingw-w64 to build C source with GCC
		you will having this binaries
			- i686-w64-mingw32* for 32-bit Windows;
			- x86_64-w64-mingw32* for 64-bit Windows.
		locate you binaries gcc mingw path and note it:
			- win32 : updatedb && locate i686-w64-mingw32-gcc
			- win64 : updatedb && locate x86_64-w64-mingw32-gcc
	2) if you have an error in the build, or if the .o object file is not present in golib/njg-ioutils/maxstdio/, run this step
		- go to golib/njg-ioutils/maxstdio folder
		- gcc -x maxstdio.x
	3) for Win32 use this env var in prefix of your go build command (recommend to use -a flag) :
		CC=/usr/bin/i686-w64-mingw32-gcc CGO_ENABLED=1 GOOS=windows GOARCH=amd64 go build -a -v ...
	4) for win64 use this env var in prefix of your go build command (recommend to use -a flag) :
		CC=/usr/bin/x86_64-w64-mingw32-gcc CGO_ENABLED=1 GOOS=windows GOARCH=amd64 go build -a -v ...

	Normally no problem will be result in the build.
