I have changed -O0 to -Og, but I also did a git pull --- I needed to do
that in order to push my corrections to SES, after all that was just
what I was initially trying to do when the crash occurred.

Now, simingly after this git pull, Emacs does not compile anymore I am
getting this.

make[2]: Leaving directory 
`/c/Programmes/installation/emacs-install/master/emacs/admin/unidata'
  CCLD     temacs.exe
sysdep.o: In function `init_random':
c:\Programmes\installation\emacs-install\master\emacs\src/sysdep.c:2122: 
undefined reference to `w32_init_random'
collect2.exe: error: ld returned 1 exit status
make[1]: *** [temacs.exe] Error 1
make[1]: Leaving directory 
`/c/Programmes/installation/emacs-install/master/emacs/src'
make: *** [src] Error 2

I had a look at the emacs git Web interface
http://git.savannah.gnu.org/cgit/emacs.git/commit/, and I am now feeling
a bit panicked, as when I did the git pull some commit was inserted
automatically just after my SES corrections, I did not pay too much
attention at this `2 commits ahead', but I now realize that in this
automatic commit there is an incredible number of files affected. I
don't know why that happened so... I hope I did not make anything too
hard to revert if need be.

  Vincent.
