On Emacs cleanup

[Angelo Graziosi <angelo.graziosi@alice.it>]

I am seeing, these days, there are a lot of cleanup and restructuring in 
Emacs trunk. The following is not much important, anyway I want to flag it.

They are a few year I build Emacs on Cygwin with this patch:

==========
diff -Naur emacs.orig/src/sheap.c emacs/src/sheap.c

    if (!bss_sbrk_ptr)
      {
        bss_sbrk_ptr = bss_sbrk_buffer;
-#ifdef CYGWIN
        sbrk (BLOCKSIZE);                /* force space for fork to work */
-#endif
      }

    if (!(int) request_size)
==========

It is very simple, and was born by the fact that someone, on this list, 
suggested me that the file src/sheap.c is used only in the Cygwin build.

If you can confirm that, perhaps applying the above patch could 
contribute to the cleanup :-)

Ciao,
Angelo.
