/*
WIN32 Build

1. Install mxe (check tutorial on http://mxe.cc)

2. After install mxe
export PATH={PATH_TO_MXE}/usr/bin:$PATH
autoreconf -fi
./configure --host=i686-pc-mingw32 --enable-blockerupter --without-curses CFLAGS=-DCURL_STATICLIB
make

3. Before starting cgminer
install WinUSB driver for detected CP2102x device with Zadig (Some users might need to reboot)
