I see. Thanks for explaining.

That would likely be more complex and more effort than adding ml64 support
to libtool.

What I did (and this worked) was to replace the command

  /bin/sh ../libtool --mode=compile ml64 -c -nologo avcall-x86_64.asm

with the sequence of commands

  ml64 -c -nologo avcall-x86_64.asm
  mkdir -p .libs; cp avcall-x86_64.@OBJEXT@ .libs/avcall-x86_64.@OBJEXT@
  sed -e 's/avcall-libapi/avcall-x86_64/g' < avcall-libapi.lo > avcall-x86_64.lo

The first line simply invokes ml64 with the given arguments.
The second line creates a copy of the .obj file under .libs/, like libtool
does for supported compilers.
The third line is a hack: it creates a .lo file, like libtool does for
supported compilers.  

Would it be possible to add support for ml64 to libtool, along these lines?

Bruno
