<div class="answer">
<p>The <tt>GNUmakefile</tt> in the top-level directory of LLVM-GCC is a special
<tt>Makefile</tt> used by Apple to invoke the <tt>build_gcc</tt> script after
setting up a special environment. This has the unforunate side-effect that
trying to build LLVM-GCC with srcdir == objdir in a "non-Apple way" invokes
the <tt>GNUmakefile</tt> instead of <tt>Makefile</tt>. Because the
environment isn't set up correctly to do this, the build fails.</p>
<p>People not building LLVM-GCC the "Apple way" need to build LLVM-GCC with
srcdir != objdir, or simply remove the GNUmakefile entirely.</p>
<p>We regret the inconvenience.</p>
