[edk2] [PATCH v2] MdeModulePkg/Core: Fix build error with old Visual Studio
Posted by Jian J Wang 7 years, 5 months ago 
> v2
> a. Change an incorrect comment on return value
> b. Change constants to macros

The build error is introduced by following check in:
  2930ef9809976ce693d1d377851344c3b06bd926
  235a4490c8ce8b6dbac49e6ae3559cb73d6bf620

The Visual Studio older than 2015 doesn't support constant integer
in binary format (0bxxx). This patch change them to decimal to fix
it.
