Updated: clisp-2.48-4

Updated: clisp-2.48-4

[Ken Brown]

The following packages have been updated in the Cygwin distribution (32-bit only):

* clisp-2.48-4
* clisp-clx-2.48-4
* clisp-gdi-2.48-4
* clisp-gtk2-2.48-4

This is a rebuild of the 2.48-3 packages to remove dependencies on obsolete 
libraries.  Because of changes in Cygwin's memory layout since 2.48-3 was built, 
I had to change the way clisp represents object pointers.[1]  There are no other 
significant changes.

For further information about clisp-2.48, see the release announcement for 
clisp-2.48-3:

I have taken over as clisp maintainer because Reini Urban, the previous 
maintainer, no longer has time to do it.  But I am not a clisp user, so I can't 
properly support it.  I will, however, try to fix any problems with my build.  I 
will also try to port clisp to 64-bit Cygwin.

Unfortunately, I have not been able to build a working version of clisp-2.49 on 
Cygwin.[2]  If there is someone more knowledgeable about clisp who wants to help 
with this (and perhaps take over as maintainer), that would be welcome.

[1] Technically, object pointers now use LINUX_NOEXEC_HEAPCODES instead of 
STANDARD_HEAPCODES.

[2] It builds, but it doesn't seem to recognize any modules.
