The pass 1 preprocessor provides a dependancy generation facility,
using --depends=D , uses teh passed in filename and changes its
extension to .d for the output filename, however this functionality is
broken. A file names one.two.three would have an output filename of
one.d and not one.two.d

The second issue is that variable setting currently cannot contain
the " character which is wrong, the attached patch fixes this and
allows for \" to include " charaters in variables.

Right, I will apply your patch.

Very well done, it looks fine ;)
I will fix this problem too, thanks for your report.

I am preparing a new upload, but will discard this fix because
backslash may appear in some locales (like iso-2022-jp) and so
must not be removed; see e.g. the first line of

Moreover this fix is fragile:
  $ cat test.1
  in test.1: $(FOO)
  #include "test.2" FOO="$(FOO)"
  $ cat test.2
  in test.2: $(FOO)
  $ /usr/lib/wml/exec/wml_p1_ipp -N -DFOO='a"b' test.1
  in test.1: a"b
  in test.2: a
So quotes need to be escaped somewhere, but I am reluctant to make such
changes.
