  Changed paths:
    M lib/sat-math.h

  Log Message:
  sat-math: Do not use __builtin_s*_overflow() with sparse.

Some versions of sparse do not understand __builtin_saddll_overflow() and
related GCC builtins for calculations with overflow detection.  This patch
avoids using them when sparse is in use.
