Hi,
I've slightly modified the boost/details/limits.hpp header file, for
MacOS X using Project Builder. The macro __powerpc__ isn't defined.
This compiler defines __ppc__ instead.
...
#if defined(__sparc) || defined(__sparc__) ||
defined(__powerpc__) || defined(__ppc__) ||
defined(__hppa)
#define BOOST_BIG_ENDIAN
...
Now, < works without a glitch.
