Hi,
I'm using Mac OS X 10.6 and I'm trying to compile a program using Clang
3.1 and libc++ but one of include files of libc++ is giving problems,
specifically one called "cmath" located in /usr/include/c++/v1/. I have
searched about this on google and I red something about building libc++
with -U__STRICT_ANSI__ param but the same errors appear. I paste here
the output:

make: *** [all] Error 2
I have built libc++ without any problem and all paths are correct, the
only thing is that the testing application "testit" is doing the tests
using the Clang version that came with XCode (which is not compatible
with Mac OSX 10.6) instead of the one that I installed with Macports. Is
there any way to define a specific compiler to do the tests?
Thank you,
