The failing command is

g++ -I/tmp/llvm/llvm-127327/include -I/tmp/llvm/llvm-127327/lib/Analysis 
-D_DEBUG -D_GNU_SOURCE -D__STDC_LIMIT_MACROS -D__STDC_CONSTANT_MACROS -O3
-fomit-frame-pointer -fno-exceptions -fno-rtti -Woverloaded-virtual -Wcast-qual

-MMD -MP -MF

"/tmp/llvm/llvm-127327/lib/Analysis/Release+Asserts/ConstantFolding.o" -MT
"/tmp/llvm/llvm-127327/lib/Analysis/Release+Asserts/ConstantFolding.d"
ConstantFolding.cpp -o
/tmp/llvm/llvm-127327/lib/Analysis/Release+Asserts/ConstantFolding.o

I'm attaching the results of this command with -E specified instead of -c .

This is on a clean checkout. I'm using Cygwin 1.7.8 on Windows XP SP3.
