Build instructions for Windows:

1. Install AMD APP SDK for Windows from here http://developer.amd.com/tools-and-sdks/opencl-zone/amd-accelerated-parallel-processing-app-sdk/
2. Get cygwin from http://cygwin.com
3. Install cygwin with the packages:
- Devel/git
- Devel/make
- Devel/gcc-core
- Python/python3
4. Start cygwin64 terminal
5. Clone repo: git clone https://github.com/mbevand/silentarmy.git
6. cd silentarmy
7. Build: make OPENCL_HEADERS="/cygdrive/c/Program\ Files\ \(x86\)/AMD\ APP\ SDK/3.0/include/" LIBOPENCL="/cygdrive/c/Program\ Files\ \(x86\)/AMD\ APP\ SDK/3.0/lib/x86_64"
8. Copy cygwin1.dll: cp /cygdrive/c/cygwin64/bin/cygwin1.dll .
9. Get your build path by typing: cygpath . -w -a
10. Create start.bat with:
c:\cygwin64\bin\python3.4m silentarmy --instances=1 -c stratum+tcp://address -u x.x -p x --use 1,2
pause

Does the Cygwin port also have issues wit multiple instances like my MSVC port?
