Cross compilation for Windows
=============================
To cross compile for Windows from Linux or OSX using the MinGW-w64 toolchain::
nim c -d:mingw myproject.nim
Use ``--cpu:i386`` or ``--cpu:amd64`` to switch the cpu arch.
The MinGW-w64 toolchain can be installed as follows::
Ubuntu: apt install mingw-w64
CentOS: yum install mingw32-gcc | mingw64-gcc - requires EPEL
OSX: brew install mingw-w64
