Subject: 24.1.50; Default argument for `save-buffer'
Date: Fri, 3 Aug 2012 02:57:27 +0200

Severity: wishlist

Hello,

Try this experiment from "emacs -Q":
  C-x b test RET hello C-x C-s M-n

(That is: create a new buffer, write something in it, try to save it and
use M-n to look for a default filename.)

The first time I try that, I see the error message "Source file
`c:/emacs/trunk/lisp/gnus/auth-source.el' newer than byte-compiled
file".  On subsequent attempts, the error message is more normal: "End of
history; no default available".

In any case, what I what to request here is that "M-n", insetead of the
error, brings to the minibuffer a default argument consisting in the
concatenation of the current directory and the name of the buffer.

TIA.

That's your local problem with byte compilation, I don't get that
message on my machine.  Just compile auth-source.el, and that message
will not appear anymore.

Have the emacs build process a way of automatically compiling every
*.elc file which is older than its *.el counterpart?  (I thought that
the plain "make" took care of this)

Yes.

> (I thought that the plain "make" took care of this)

No.  The correct procedure for building on Windows after updating from
bzr is this:

  cd nt
  configure
  make
  cd ../lisp
  make bzr-update
  cd ../nt
  make
  make info

The 'configure' step can be omitted if none of the configury files
changed (that includes makefile.w32-in files, nt/config.nt, and
nt/configure.bat itself).

Some changes are too invasive, and make the "make bzr-update" stage
fail.  If the problems don't go away after re-running that stage
several times, your best bet is a full bootstrap.
