llvm dev - Oct 2009 - [LLVMdev] GlobalValue.h:116 error

When I attempt to follow any tutorial for llvm and add the `llvm-config
--cxxflags --ldflags --libs all` line to my GXX_FLAGS, g++ chokes on
llvm/GlobalValue.h, complaining of an invalid cast from int to
llvm::GlobalValue::LinkageTypes. I receive this error under both Red Hat and
Ubuntu and the version of G++ I am using is 4.1.2.
Thanks in advance,
Jared

I solved it by moving a project-specific include after the llvm includes.
I.e.,
From:

#include "ast.h"
#include "llvm/Module.h"
#include "llvm/Function.h"
#include "llvm/PassManager.h"
...

to:

#include "llvm/Module.h"
#include "llvm/Function.h"
#include "llvm/PassManager.h"
...
#include "ast.h"

I can't figure out why this gave me the particular error I was receiving,
but it solves the problem.
