 UINT*_MAX and stdint.h are governed by the C99 standard (Section
 7.18). A footnote in that that section states that "C++
 implementations should define these macros only when
 __STDC_LIMIT_MACROS is defined before <stdint.h> is included."  The
 system headers in FreeBSD and many other implementations follow this
 recommendation.  If you want to use these macros in C++ code
 unconditionally, then you should include <cstdint> instead, as
 described in the C++11 standard ( the cstdint.syn section in Chapter
 18).  You probably ought to be doing this anyway.
