DynamicLibrary.inc compile error /w vc++2005 and windows sdk 6.1

Hello there,
I'm having a problem compiling llvm with vc++ 2005 and windows sdk6.1. It seems that the Platform SDK supplied with vc++2005 uses PSTR for the first param of PENUMLOADED_MODULES_CALLBACK64 typedef (dbghelp.h) and the windows sdk 6.1 (also windows sdk 6.0a that ships with vc++2008) uses PCSTR. The _MSC_VER macro guard for ELM_Callback(...) kinda kills the possibility of using VC++2005 with SDK 6.1 and without the macro guard, one will require to have SDK6.0A+ setup with vc++2005. Is there any known workaround to this issue?

1>d:\dev\llvm\lib\system\Win32/DynamicLibrary.inc(116) : error C2664: 'EnumerateLoadedModules' : cannot convert parameter 2 from 'BOOL (__stdcall *)(PSTR,llvm::ModuleBaseType,ULONG,PVOID)' to 'PENUMLOADED_MODULES_CALLBACK'

I saw one old post from 2007 titled "LLVM 2.1 with VC++" in this list stating the same thing but this wasn't fixed probably due to failure to reproduce. Any suggestion would be appreciated. Thanks.
