a card-carrying statistician). Relevant changes from version 3.52.9:
Switched to using sigsetjmp/siglonjmp when available to
preserve signal masks (allows CONTROL-C to work on Linux).
Modified startup to start hidden and minimized if -Embedded is
in the command line.
Cleaned up get-decoded-time.
Removed savesys.lsp from distribution to force using
save-workspace directly when building the mac or windows
workspaces. Using save-workspace from within a file means
some special variables are bound.
Added support for FreeBSD (enabled standard IEEE handling of
floating point zero divide).
Added SYSTEM:TYPED-VECTOR-ELEMENT-SIZE.
Added unsigned C character to typed vector types.
Added cptr-protect to add values onto list of values protected
by a typed pointer.
Added user exit functions.
Added support for weak boxes.
Added binding of *print-readably* to nil around default
handler printing code and around do-debugger to avoid
recursive errors.
Added new customizable DDE server.
Added minimal implementations of copy-readtable, readtablep, and
set-syntax-from-char.
Added error check for non-integer index in select.
Fixed defpackage to prevent duplicate nicknames.
Fixed structure printing to inherit print functions.
Fixed lisp2ulong to signal an error for negative instead of
positive arguments.
Fixed buffer underflow problem in floating point formatting.
Fixed make-string to check for negative length argument.
Fixed some documentation mismatches.
