Hi

On a cygwin/win7/x86_64 platform, building LLVM 3.4 fails as

llvm[1]: Linking Release+Asserts Shared Library cygLLVM-3.5.0svn.dll

configure.log is
This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.

It was created by LLVM configure 3.5.0svn, which was
generated by GNU Autoconf 2.60.  Invocation command line was

  $ ../llvm/configure --enable-targets=x86_64 --enable-optimized
--enable-shared=yes --disable-embed-stdcxx


Any idea what could be wrong in building LLVM?

TIA
