Hi,

i don't consider it as a bug, it works as expected.

Maybe you want something like
  <set-var GFONT_BASE="$(ROOT)/img/$(WML_SRC_BASENAME)">

It isn't sufficient if you have duplicate filenames.
In that case, let's play with the pass 2:

# rel-path is the ``end'' part of the path, with ROOT removed
   <set-var rel-path=<match $(WML_SRC_DIRNAME)
        <concat <subst-in-string $(ROOT) "\\.\\." "[^/]*">$>
        action=extract>>
   <set-var GFONT_BASE=<concat
      "$(ROOT)/img/"
      <subst-in-string <get-var rel-path> "/" "_">
      "_$(WML_SRC_BASENAME)">>

In the top .wmlrc, define the ROOT variable like this:
  -DROOT~.

Then when running wml on $(ROOT)/foo/bar/baz.wml,
  $(ROOT)/img/foo_bar_baz.gfont000.gif ...
are generated.
