  $ ./configure '--host=i586-mingw32msvc' '--disable-shared'
  checking format of `double' floating point... od: conftest: No such
  file or directory
  od: conftest: No such file or directory
  configure: WARNING: Could not determine float format.
  configure: WARNING: Conversions to and from "double" may be slow.

  One needs to change "conftest" to "conftest$EXEEXT".
  Patch attached.

The compilation command omits $EXEEXT and so does the od command.  Thet
looks consistent to me, so it should work.  Why does that not work on
DOS?  Will the compiler naughtily append .exe anyway?
