I wrote an evil sed script to generate globals.h from the .c files.
I used sed and not anything nicer since that is what the GNU coding
standards specify.

It is rather slow.  On my laptop it takes 10 seconds to scan src/*.c.
This would have to be done with every change to a .c file.

I've appended the script in case you want to try it yourself.
This is just generating the body of the "emacs_globals" struct; some
minor tweaks remain to be done in the Makefile.

Maybe Andreas' idea of reusing the doc extractor would be better.
I have not looked at that.
