new beta release

[Bruno H. <br...@cl...>]

Hi all,

clisp 2.49.90 is available at
  https://haible.de/bruno/gnu/clisp-2.49.90.tar.bz2

I invite you all to poke around with it, and report problems, since I'd like
to see a 2.50 release soon that is as robust as possible.

Features of this beta release (please report issues about it):
  * Portability - see NEWS file
  * Many object representations are supported - please use the
    'multibuild-<platform>' target of Makefile.devel to test all of them.
  * FFI is supported on all platforms except HP-UX.

Not in the scope of this beta release (no need to report issues on these):
  * Native Windows ports (mingw and msvc).
  * Multithreading.

Bruno
