Subject:	Re: Emacs works under v2.0!

   Here is the scoop: amazingly enough, any library function that gets a
   pointer to a text in an Emacs buffer, cannot call `malloc', because GNU
   malloc can cause relocation of the buffer, which invalidates the passed
   pointer.  And our `write' does just that when it writes to a text file. 
   Since `write' will probably be fixed anyway in the future release, for the
   time being I just overloaded `__write' on src/msdos.c. 

Aha!  That was why my alloca-based hack happened to solve the
problem.

   If everything goes according to plan, you should see an Emacs pretest in a
   day or two that should build cleanly under v2.0, and v2 support should be
   part of the official Emacs 19.31 distribution.  (Can you imagine to launch
   a compilation, or shell out to DOS, and see the results lightning-fast
   instead of waiting for Emacs to page itself out?)

It ticked into the source yesterday.  Good work!
