svn commit: r229494 - head/sys/powerpc/include

[Andreas Tobler]

Author: andreast
Date: Wed Jan  4 16:02:52 2012
New Revision: 229494
URL: http://svn.freebsd.org/changeset/base/229494

Log:
  Introduce internal macros for __U/INT64_C to define the U/INT64_MAX/MIN
  values properly. The previous definition only worked if __STDC_LIMIT_MACROS
  and __STDC_CONSTANT_MACROS were defined at the same time.
