With MinGW, I get:

  checking for libintl.h... yes
  checking for inline... inline
  checking gawkextlib.h usability... no
  checking gawkextlib.h presence... no
  checking for gawkextlib.h... no
  configure: error: Cannot find gawkextlib.h.  Please use --with-gawkextlib to 
supply a location for your gawkextlib build.

And after I overcome that obstacle, I get this from "make":

That sounds like trouble, right?

Thanks.
