# Makefile to build the Windows SDK under linux.
#
# This file is included by build/core/Makefile when a PRODUCT-sdk-win_sdk build
# is requested.
#
# Summary of operations:
# - create a regular Linux SDK
# - build a few Windows tools
# - mirror the linux SDK directory and patch it with the Windows tools
#
# This way we avoid the headache of building a full SDK in MinGW mode, which is
# made complicated by the fact the build system does not support cross-compilation.

# We can only use this under Linux
