I didn't look too deep, but it seems that wmemu was compiled with an
incompatible set of header files or an early beta version of a library. 
`__djgpp_exception_state' is #defined on <sys/exceptn.h> to be
(*__djgpp_exception_state_ptr), but the source of WMEMU doesn't include 
that header.  Maybe you should get the sources and recompile the WMEMU 
library?  )If you do, note that you must include <setjmp.h> before 
<sys/exceptn.h>, or it won't work.)

If and when you find what was wrong, please tell here, so that if there is
a bug it could be corrected, and the FAQ updated if needed.  (And yes,
WMEMU should allow you to debug FP code on a FPU-less machine.)
