1# Makefile to build the Windows SDK under linux.
2#
3# This file is included by build/core/Makefile when a PRODUCT-sdk-win_sdk build
4# is requested.
5#
6# Summary of operations:
7# - create a regular Linux SDK
8# - build a few Windows tools
9# - mirror the linux SDK directory and patch it with the Windows tools
10#
11# This way we avoid the headache of building a full SDK in MinGW mode, which is
12# made complicated by the fact the build system does not support cross-compilation.
13
14# We can only use this under Linux with the mingw32 package installed.
