I am afraid that I don't quite understand the meaning of what you say 
above.  Hopefully a replacement power supply will lead to 
clarification.

It seems that with MinGW, packages which are explicitly instrumented 
to be Windows DLLs cause more harm than good.  The bzip2 header causes 
more harm than good since its defaults are not correct for usage of 
the DLL library (defaults to symbol import rather than export).  A 
dependent package can not intelligently know if the library will be 
(is) static or DLL. Autoconf does not make any provision for including 
additional header files when testing for library symbols.

I am glad to hear that libwmf works for you.
