These are some minimal changes to compile with C++. Here begins
the road to rewriting the bjam engine in C++. So far this is only built
and tested with XCode clang on OSX.
Boost.Build system with clang. I also fixed a few things in the clang-linux
toolchain;
- Clang doesn't support -pg.
- Adding -O0 to turn optimization off is silly, because it is set to zero by
default if omitted on the command line. The compiler will whine about
unused options if you later add another -O flag. The Boost.Build UTF
interface adds a second -O0, so you end up with two redundant command line
options and a warning from bjam/clang for every invocation of the compiler
when using the test framework.
