Re: [PATCH 1/6] BaseTools/CommonLib: avoid using 'native' word size in IP address handling

["Gao, Liming" <liming.gao@intel.com>]

Ard:
  I mean the build error. Besides, what test have you done with this patch set?

CommonLib.c(1651): error C2220: warning treated as error - no 'object' file generated
CommonLib.c(1651): warning C4133: 'function': incompatible types - from 'UINTN *' to 'UINT64 *'
NMAKE : fatal error U1077: '"C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\BIN\cl.exe"' : return code '0x2'
