[flext] flext and "cassert"

[Nick Burge]

Hello Thomas, attempting to compile flext on my macbook pro (osx lion) the compilation halts with:


clang: warning: treating 'c-header' input as 'c++-header' when in C++ mode, this behavior is deprecated
clang: warning: argument unused during compilation: '-ftree-vectorize'
In file included from source/flext.h:65:
In file included from source/flclass.h:23:
In file included from source/flbase.h:23:
source/flstdc.h:35:10: fatal error: 'cassert' file not found
#include <cassert>

I have xcode 4.5.1 installed with the command line utilities and use the command /.build.sh pd gcc
Can you shed any light please?
Nick.
