# Rewrite the include path for runfiles.h in runfiles_src.cc, and create

# We cannot just check in runfiles_src.{h,cc} as runfiles.{h,cc}, because it'd
# cause a header check failure on Windows when building targets in the Bazel
# source tree, if those targets depend on @bazel_tools//tools/cpp/runfiles,
# because due to lack of sandboxing they would accidentally pick up runfiles.h
