[MiKTeX] MiKTeX-2.7 & `save size'

[Alexander G. <A....@fz...>]

Hello,

With MiKTeX-2.6 documents such as

ftp://ftp.fzd.de/private/grahn/animate_example.tex

compiled without error using pdflatex and the animate.sty package to
produce an animated PDF document (to be viewed in Adobe Reader 7) from
the multipage PDF

ftp://ftp.fzd.de/private/grahn/frames.pdf

However, with MiKTeX-2.7 a `TeX capacity exceeded' is generated:

  Y:\AO2F3E~Z\DOC>pdflatex animate_example
  This is pdfTeX, Version 3.141592-1.40.4 (MiKTeX 2.7)
  ...
  ! TeX capacity exceeded, sorry [save size=5000].
  \@anim@newkey #1#2->{
                       \expandafter \xdef \csname #1\endcsname {#2}}
  l.38   ]{12}{frames}{}{}
  
  !  ==> Fatal error occurred, no output PDF file produced!
  Transcript written on animate_example.log.

Consequently, I tried to increase `save size' using the --save-size
option according to the pdftex manual page, but with no avail:
  
  Y:\AO2F3E~Z\DOC>pdflatex --save-size=1000000 animate_example
  This is pdfTeX, Version 3.141592-1.40.4 (MiKTeX 2.7)
  entering extended mode
  ! Undefined control sequence.
  <*> Y:\AO
           2F3E~Z\doc\--save-size
  ? x
  !  ==> Fatal error occurred, no output PDF file produced!

What is wrong with the above command line? Is there a way to permanently
change the save size within some configuration file?

(I am using Windows Server 2003 and command.com as the shell, because
cmd.exe has been disabled by our administrator.)

Thanks for any recommendation,

Alexander
