           Summary: __has_include does not work correctly (compilation
                    fails)
           Product: clang
           Version: trunk
          Platform: Macintosh
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: Frontend
        AssignedTo: unassignedclangbugs at nondot.org
        ReportedBy: mimomorin at gmail.com
                CC: llvmbugs at cs.uiuc.edu


The following code fails to compile (tested on release build of trunk and
clang-3.0 rc1). 

#include <iostream>

int main (int argc, char* argv[])
{
    std::cout << __has_include(<iostream>) << std::endl;

    return 0;
}

Here is the error messages.
Assertion failed: (ParsingPreprocessorDirective && ParsingFilename == false &&
"Must be in a preprocessing directive!"), function LexIncludeFilename, file
llvm/tools/clang/lib/Lex/PreprocessorLexer.cpp, line 33.
