David,
Sorry about the extra revision here to fix the libc++ header detection
on 10.7 as well.
% clang++-3.4 -stdlib=libc++ hello.cc
hello.cc:1:10: fatal error: 'iostream' file not found
#include <iostream>
^
1 error generated.
I assumed that libc++ header detection was already functional on 10.7. So
in llvm34-3.4.1-0a/c, the system libc++ header detection as broken on all
three targets of the 10.7 tree.
I don't think Apple ever has ever placed the system libc++ headers in
default path of /usr/include/c++/v1 but rather always found these headers
via a path relative to the executing compiler binary's location.
After completing 'fink -m -l' bootstraps on 10.7, 10.8 and 10.9 as
well as manual verification on all three targets that 'clang++
-stdlib=libc++' found the system libc++ headers, I committed the following
change to the 10.7 tree.

# needed for gcc-fsf-4.x only
This same change to the PatchScript also needs to be backported to the
llvm33 package so it can find the system libc++ headers as well.
