Tidying of CL files; make docstrings read better, remove commented-out code 2010-05-30 Aidan Kehoe <kehoea@parhasard.net> * cl.el: Remove extraneous empty lines. Remove the commented-out Lisp implementation of #'last, #'copy-list. Remove #'cl-maclisp-member. (acons, pairlis): Have the argument list reflect the docstring for these functions. * cl-macs.el (defun*): Have the argument list reflect the docstring. Document the syntax of keywords in ARGLIST. (defmacro*): Have the argument list reflect the docstring. Document &body, &whole and &environment. (function*): Have the argument list reflect the docstring. (loop): Have the argument list reflect the docstring. (eval-when, dolist, dotimes, do-symbols, flet, labels, macrolet, symbol-macrolet): Specify the argument list using the arguments: (...) syntax. (define-setf-method, rotatef, defsubst*): Have the argument list reflect the docstring. (letf, letf*): Specify the argument list using the arguments: (...) syntax. (svref, acons, pairlis): Add compiler macros for these functions. * cl-extra.el: Remove the commented-out Lisp implementation of #'equalp. If we want to look at it, it's in version control. (cl-expt): Remove this. The subr #'expt is always available. Call #'cl-float-limits at dump time. Remove the commented-out Lisp implementation of #'subseq. (concatenate): Use (error 'invalid-argument ...) here, if TYPE is not understood. (list-length): Don't manually get the length of a list, call #'length and return nil if the list is circular. * byte-optimize.el (equalp): This needs byte-optimize-binary-predicate as its optimizer, as do the other equality predicates.

/* Building under cygwin
 *
 * The approach I have taken with this port is to use primarily the
 * UNIX code base adding stuff that is MS-Windows specific. This works
 * quite well, and is in keeping with my perception of the cygwin
 * philosophy.  Note that if you make changes to this file you do NOT
 * want to define WIN32_NATIVE (formerly "WINDOWSNT"), I repeat - do
 * not define this, it will break everything horribly. What does get
 * defined is HAVE_MS_WINDOWS, but this is done by configure and only
 * applies to the window system.
 *
 * When building make sure your HOME path is unix style - i.e. without
 * a drive letter.
 *
 * once you have done this, configure and make.
 *
 * windows '95 - I haven't tested this under '95, it will probably
 * build but I konw there are some limitations with cygwin under 95 so
 * YMMV. I build with NT4 SP3.
