# Experimental config for building on Windows via clang-cl.
# As an aspiration, it may eventually not be required to manually
# activate this config, but for now, it is a place to store the
# set of flags and tweaks needed to get the Windows build working.
# Note that this is intended to work with clang-cl, not the Visual
# Studio compiler. The following must be performed prior to invoking
# Bazel:
#   * Install Visual Studio Build Tools
#   * export USE_CLANG_CL=1
#   * export BAZEL_LLVM=C:/Users/$USER/scoop/apps/llvm/current
#     (or actual LLVM install location)
# Then one can build with:
#   bazel build --config=windows {targets...}

# Works around __TIME__ __DATE__, etc redefinitions and -std=c++14
# warnings.

# Enables unix-style runfiles link trees (requires symlink permission).

# system settings.
