<pre>Which is required to get libc++ includes living alongside the 'c-index-test'
binary on MacOS.
Specifically, this would fail on Mac even if libc++ is built and lives
alongside c-index-test:
<span class="quote">> $ cat test.cc
> #include <iostream>
> $ ./bin/c-index-test -write-pch foo.pch test.cc
> test.cc:1:10: fatal error: 'iostream' file not found</span >
This happens because write_pch_file from c-index-test.c filters out first three
command-line args and uses 'clang_parseTranslationUnit2'. If it called
'clang_parseTranslationUnit2FullArgv' and passed argv[0] this would fix the
issue.
Note that the other functions in 'c-index-test.c' also have this problem.
