Hi Mike,

  I think that this is more of a documentation problem than anything.

  Would you be happy with a rewording of the description of the -m option
  so that it said:

     -m <machine>
          Specifies the type of machine for which the library file 
          should be built.  dlltool has a built in default type, 
          depending upon how it was created, but this option can be 
          used to override that.  This is normally only useful when 
          creating DLLs for an ARM processor, when the contents of 
          the DLL are actually encode using Thumb instructions, or
          DLLs for the x86 architecture when dlltool is built for 
          the x86_64 architecture.

          Note - it may be necessary to use the "-f <option>" command
          line option to instruct whichever assembler is being used to 
          create binaries appropriate for the <machine> targeted by 
          the -m option.  So for example when using "-m i386" it may 
          also be necessary to specify "-f --32".

  The point being that there is no guarantee that the assembler being
  used is the GNU assembler, and so some option other than --32 might 
  needed in order to generate 32-bit binaries.  Hence -m cannot safely
  infer which -f option should be used.

Cheers
  Nick
