If an uninterned symbol in a \"normal\" package is read, the resume option is still allowed. (The proceed message is somewhat misleading, though.) 3) The name READ-INTERN-SOFT was somewhat of a misnomer, since it always signalled some error or other when a symbol was not found.

This patch creates a warm-initialization to redraw the labels on every window. (We don't know how many, where, may have been clobbered.) To facilitate this, (:METHOD TV:ESSENTIAL-LABEL-MIXIN :REDRAW-LABEL) is provided. It erases, then draws, a window's label.

It was using SI:COPY-OBJECT-TREE to copy all levels of its args in temporary areas. With GC, this isn't needed; and, compile-time forms are usually simple enough, that we shouldn't have to be paranoid (and time-consuming) about copying 12 levels of structure!

Give it a second value I can use to recognize when compiler style checkers have issued a warning as their last act (all that I can find do so). Note that (from now on) style checkers should respect this convention that, when a style violation is detected, the last thing done before exit is to call COMPILER:WARN appropriately." "keith" NIL 2799294415) (83 "Implement less simple-minded compiler style checking. Compiler was invoking style checkers on every call to optimize a given form. This frequently causes duplicate warnings for a given mis-formed call. Also, it is very easy to generate multiple duplicate errors within one DEFUN; typically, only one warning is enough to show the user what to change. New scheme is controlled by compiler variable, so those who want lots of compiler warnings can turn the new feature off. The variable doc string explains how it works: (defvar *just-once-for-style-checkers-per-inner-form* T \"If non-NIL, user only gets one style-check warning within a top-level form, for a given combination of style-checker function and form (function call). T means condense for all style-checkers; can also be a list of style-checker functions to condense in this fashion.\")" "keith" NIL 2799296261) (84 "Better SI:SELECT-PROCESSOR. More informative messages for ill-formed clauses. Use a style checker at compile time to note missing/bogus processor codes. (Now we don't get double the warnings, double the fun.)

Enthusiasts note: also implemented a way to style-check a function call against the published, \"human readable\" argument list, when it differs; e.g, STRING-SEARCH, which supports two different calling sequences, and only gets checked at compile time for &REST ARGS, not keywords. The existing style check mechanism for doing that was lame, and the general fix was useful elsewhere."

Current state of thought is that the compiler should fold in constants defined by DEFCONSTANT when they are EQL-comparable objects. Recent patch to do this wasn't working. This patch fixes bug from that patch in handling of the 'COMPILER:CONSTANT-FOR-COMPILATION property.
