Hi,

I recently installed LLVM on a Gentoo Linux x86 system, and ran into an internal
compiler assertion failure while trying to compile some simple code.  There is a
workaround, but since a bug report was advised, I decided to file one.

The code, in a file called hello.c:
===================================
#include <stdio.h>
int main() {
    printf("hello world\n");
    return 0;
}

The command line:
=================
llvm-gcc -o hello hello.c

The output, including the assertion failure:
============================================
In file included from hello.c:1:

Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://llvm.cs.uiuc.edu> for instructions.

The workaround: Use -I to find the include file mentioned:
==========================================================
llvm-gcc
-I/usr/local/bin/llvm/cfrontend/x86/llvm-gcc/lib/gcc/i686-pc-linux-gnu/3.4-llvm/include/
-o hello hello.c
