Patch looks good to me,

However I suspect my testing of predef is not covering the test cases
100%, I am able to confirm that the build failure I had building predef
/test from status folder is gone. I tested both svn and git layouts and
they are OK.

My concern is that I get warnings related to objective-c* on my Ubuntu
box running ../b2 in status folder. Note that these warnings are not new
and are not introduced by patch :

     - valgrind : yes (cached)
warn: Unable to construct ../libs/predef/test/info_as_objcpp
warn: Unable to construct ../libs/predef/test/info_as_objc

I don't know much about Objective-C/C++ or how these tools are supposed
to work in b2. In addition to default toolset (gcc) I tried clang
toolset, but I got the same warnings. I looked into installing gnustep,
but it was not trivial and I don't have time to look into it.

How relevant are these warnings for verifying correctness of this patch?

The best thing is probably if someone with an Apple system can try it,
preferably in both layouts.
