Sent.

It compiles, but the backends don't work.

Ok, I send the diffs to you.

I did not try it for SANE, but for XSane which is less complex
it worked with the following additional changes:

1. in src/Makefile.in:

Add

OBJEXT = @OBJEXT@
EXEEXT = @EXEEXT@

at the beginning of Makefile.in

change of
BINPROGS = @BINPROGS@
to
BINPROGS = @BINPROGS@$(EXEEXT)

change all
.o
to
.o$(OBJEXT)

change

xsane: $(XSANE_OBJS) $(LIBLIB)
to
xsane$(EXEEXT): $(XSANE_OBJS) $(LIBLIB)


Perhaps I should test this first and then send you a complete list,
but I don't have too much time now and I'm on holidays in December.
But I could work on this in January.

2. I've been told, that there is a newer version of mkinstalldirs
   which supports drive-letters (there is one included in a
   autoconf 2.50 - package for OS/2) but I don't know if it
   works on unix'es too. I also sent you this new one.
