<pre>When compiling paths rooted at /Users will be mis-handled as macro
undefinitions rather than input resulting in a "no input files provided" error.
This is somewhat bewildering until one realizes what is happening. This is
also possible to hit on Windows as the default home directory there is now
C:\Users\... and since the driver letter can be elided on the same drive, and
windows will canonicalize / to \ as a dir separator, it is valid to pass
/Users/... as an input to clang.</pre>
