18 Processor or Compiler specific defines and types for IA-32.
19 We are using the ANSI C 2000 _t type definitions for basic types.
20 This it technically a violation of the coding standard, but they
21 are used to make EfiTypes.h portable. Code other than EfiTypes.h
22 should never use any ANSI C 2000 _t integer types.
