Hi Geert,

I assume you have already found the "undumped" tarball, and are using
that to undump.  (There is a known problem that an already dumped
emacs.exe cannot dump itself again.)

If indeed PURESIZE is the problem, then yes you will need to recompile
Emacs with that value increased.  You can compile Emacs with gcc - I
made an "alpha" release of that for 20.7, and it is supported as
standard in 21.1 (due for release quite soon).

Look in 

  ftp://alpha.gnu.org/gnu/windows/emacs/mingw-trial/

for the version of 20.7 that compiles with GCC + Mingw.

Look at src/puresize.h for values to change.
