annotate src/sysfloat.h @ 5658:289cf21be887
Don't augment ENVIRONMENT when that's not indicated, #'macroexpand.
This reflects better understanding on my part of the &environment macro
keyword, and I've expanded the Lisp manual and docstrings to reflect that.
lisp/ChangeLog addition:
2012-05-06 Aidan Kehoe <kehoea@parhasard.net>
* cl-macs.el (block): Comment on why we can't use &environment
here.
* cl-macs.el (defmacro*): Document &environment in more detail.
* cl-macs.el (macrolet): Use &environment, instead of referencing
byte-compile-macro-environment directly.
* cl-macs.el (symbol-macrolet): Ditto.
* cl-macs.el (lexical-let): Ditto.
* cl-macs.el (labels): Ditto.
man/ChangeLog addition:
2012-05-06 Aidan Kehoe <kehoea@parhasard.net>
* lispref/macros.texi (Expansion):
Cross-reference to documentation of #'cl-prettyexpand, #'defmacro*
when talking about #'macroexpand.
tests/ChangeLog addition:
2012-05-06 Aidan Kehoe <kehoea@parhasard.net>
* automated/lisp-tests.el:
Use &environment appropriately in #'macrolet, instead of relying
on #'macroexpand to guess what we mean.
