Author: smeenai Date: Wed Apr 5 23:47:49 2017 New Revision: 299625 URL: http://llvm.org/viewvc/llvm-project?rev=299625&view=rev Log: [libc++] Respect Windows Store app CRT restrictions
Some CRT APIs are unavailable for Windows Store apps [1]. Detect when we're targeting the Windows Store and don't try to refer to non-existent CRT functions in that case. (This would otherwise lead to a compile error when using the libc++ headers and compiling for Windows Store.)
