Patches for Corman Lisp 2.5
---------------------------

If you add these patches to your system, we recommend that you
add all of them (to a 2.5 release installation) because some may
depend on others. Rebuild CormanLisp.img according to instructions
in the Corman Lisp 2.5 manual, p. 23.


The following files contained here should update the files in the appropriate 
directories:

sys/destructure.lisp
    Included Carlos Ungil's patch to DESTRUCTURE-BIND to handle keywords with 
    differing variable names.

sys/defpackage.lisp
    Fixed a problem with DEFPACKAGE that caused COMPILE-FILE to fail.

sys/misc-features.lisp
    Adds the common lisp function WITH-OPEN-STREAM.

sys/hash-table.lisp

    This fixes REMHASH  and CLRHASH to update the HASH-TABLE-COUNT correctly.
    It also provides a faster implementation of REMHASH.
    
sys/math2.lisp

    Fixes a problem when reading literal negative floats with negative exponents.

sys/xp.lisp

    Added support for :readably option to WRITE function.
    This provides ANSI compatibility and corrects an issue with 
    ct:TRANSCRIBE-FILE.
    Corrects the way file columns are retrieved, which affects pretty printing to 
    streams other than the console.

sys/math.lisp
    Fixed a problem with ISQRT. The kernel function could give incorrect 
    results when applied to a bignum with integer-length even. This is 
    redefined to override the kernel function (which will be updated in 
    the next kernel update).
    
sys/array.lisp
    UPGRADED-ARRAY-ELEMENT-TYPE now returns 'character for subclasses of 
    character (standard-char and base-char). This fixes a problem with MAKE-ARRAY
    where arrays of base-char were not being treated as strings.
    
    3/8/05: An error is thrown if the requested array size exceeds ARRAY-TOTAL-SIZE-LIMIT.
    
sys/time.lisp
    Redefines TIME macro and INTERNAL-TIME-UNITS-PER-SECOND to properly handle 
    systems which return a value greater than 2^31 for QueryPerformanceFrequency.

CormanLispServer.dll
    The kernel has been modified to generate an error, rather than hang, if the 
    memory heap reserve size is exceeded.
    Increased the default reserve heap size from 128 megs to 256 megs.

CormanLispServer/gc.cpp
    Source code changes to kernel to support above memory modifications.
