Bootstrap fails on Win32

[B. Anyos]

Hi,

Doing a bootstrap compilation fails with file 'characters.el'
The problem reported is:

  make[1]: *** No rule to make target `../lisp/international/characters.elc', 
needed by `DOC'.  Stop.

When I tried to compile it manually I got the following error message:

  > emacs.exe -batch -f batch-byte-compile characters.el
  Loading d:/Personal/CVS/emacs/lisp/international/uni-category.el (source)...

  In toplevel form:
  characters.el:1136:1:Error: Symbol's value as variable is void: this-val

Checking the history this section was recently added to revision 1.76 about a 
week ago.
Can someone fix this please?

Thanks,
 Bela
