It should look something like this:

Libtool is definitely confused since it's not got the right 'cyg' prefix for
the dll in CJ's version, and it's forgotten the .a suffix for the import
library, meaning it'll overwrite (or be overwritten by) the DLL.
I think we had something like this a while back when gomp was enabled but
fortran not configured in. Hang on.... PR41418. Same symptoms. Haven't
verified if there's a similar cause yet, am bootstrapping r156219 ATM.
