I am not sure but it looks like a problem with your Cygwin instillation ?

Try a 'make configure' or 'make reconfigure'.

Here's a link to the instructions I developed for building LLVM on Cygwin :-


As far as I know it should hopefully still be correct for the debug build. 
It failed on the release build though due to a bug in ld, which hopefully 
will be fixed with time.
