[cfe-dev] Undefined reference cross-compiling shared llvm/clang for mingw

[Abramo Bagnara]

Using the following configure command:

../llvm-r136065/configure --host=i586-mingw32msvc
--enable-targets=host-only --disable-jit --enable-bindings=none
--enable-shared --disable-threads --disable-pthreads
--disable-assertions --disable-optimized

I get a bunch of undefined reference on each executable linking, the
first lines listed below.

I've verified that replacing --enable-shared in configure command line
with --disable-shared the errors disappears.

Someone knows why this happens?
