+# We have some triples which are bootstrapped from other triples, and this means

+# For example, MSVC requires the llvm-ar.exe executable to manage archives, but

+# add this directory to PATH when executing new processes:

+# 	$SYSROOT/rustlib/x86_64-pc-windows-gnu/bin

+# To remedy this problem, the rules below copy all native tool dependencies into
