The first hunk works around the combination of:
  - NetBSD stdint.h/int_limit.sh not defining UINT_LEAST64_MAX in c++
     mode before C++11
  - ufraw including C headers in C++ mode
  - ufraw being C++03
by just asking for the limit macros to be defined.

\todo Explain second hunk.  This seems to be about avoiding a SWAP macro
and is likely not very interesting.
