        <pre>Afternoon,

On Redhat 6.5 uchar.h is in /usr/include/unicode

When running "make check-libcxx", there is a failure in the check:

The lit test:
llvm/projects/libcxx/test/std/depr/depr.c.headers/uchar_h.pass.cpp
    fails because it can't find the header uchar.h as an include file.  

My dirty fix is to append unicode to uchar.h so line becomes:
#include <unicode/uchar.h>

  This passes the test, but I regret that I've not enough knowledge of the
entire cmake/lit structure to know where is the best place to add an additional
item to the INCLUDE_PATH list such that only the lit test is affected.  On the
other hand, I guess the PATH may also need to be part of the libcxx header
search path for the library.

I hope this is enough information for you to pursue addressing this issue.

Thanks.</pre>
