[LLVMdev] missing llabs define in VS: DAGCombiner.cpp

[W Shumaker]

grumble, grumble, MS does not have llabs()
llabs() is not defined in Visual Studio, however, _abs64() is. But if I switch to
_abs64() the linker does not resolve __abs64(). I thought _abs64() was suppose
to be in the CRT library. Any hints for a solution?

c:\devwl\llvm\lib\CodeGen\SelectionDAG\DAGCombiner.cpp(295) : error C3861: 'llabs': identifier not found, even with argument-dependent lookup
