<rdar://problem/13479214> Make Clang's <stddef.h> robust against system headers defining size_t/ptrdiff_t/wchar_t. Clang's <stddef.h> provides definitions for the C standard library types size_t, ptrdiff_t, and wchar_t. However, the system's C standard library headers tend to provide the same typedefs, and the two generally avoid each other using the macros _SIZE_T/_PTRDIFF_T/_WCHAR_T. With modules, however, we need to see all of the places where these types are defined, so provide the typedefs (ignoring the macros) when modules are enabled. llvm-svn: 177686 2013-03-22 08:10:49 +08:00			`@import StdDef.Other;`

[modules] Simplify -cc1 interface for enabling implicit module maps. We used to have a flag to enable module maps, and two more flags to enable implicit module maps. This is all redundant; we don't need any flag for enabling module maps in the abstract, and we don't usually have -fno- flags for -cc1. We now have just a single flag, -fimplicit-module-maps, that enables implicitly searching the file system for module map files and loading them. The driver interface is unchanged for now. We should probably rename -fmodule-maps to -fimplicit-module-maps at some point. llvm-svn: 239789 2015-06-16 08:08:24 +08:00			`// RUN: %clang_cc1 -fmodules -fimplicit-module-maps -fmodules-cache-path=%t -I %S/Inputs/StdDef %s -verify`
