autoconf error on Windows

[Alec Taylor]

Thanks, adding MSYS's bin to PATH solved that issue.

Now I'm getting linker errors on:

C:\libraries\MinGW\bin\gcc.exe -mno-cygwin -shared -s
build\temp.win-amd64-2.7\Release\src\winrand.o
build\temp.win-amd64-2.7\Release\src\winrandom.def -LC:\Python27\libs

-o "C:\Projects\satchmo_test\Prototype\src\pycrypto\lib\Crypto\Random\OSRNG\winrandom.pyd"
