[Gimp-docs] authors.xml not build

[Kolbjørn Stuestøl]

The authors files are not build.
Updated gimp-help-2, run "make -f Makefile.GNU pot", "make -f 
Makefile.GNU xml-no" and "make -f Makefile.GNU po-no".
When running "make -f Makefile.GNU validate-no" I get the following 
message: "xml/no/preface/authors.xml:1: parser error : Document is 
empty" + some other errors because of this error.
I thought the file should be generated automatically, but what 
command(s) do I miss?
As a result, when trying to make html I get
$ make -f Makefile.GNU html-no
*** Copying images (no) ...
*** Making html for no ...
make: *** [html/no/index.html] Error 53
What is btw error 53? Where do I find an error list?

(I'm running Cygwin on Windows XP).
