Package: emacs

I just bootstrapped (or in fact, build at all) after two weeks and
suddenly I'm getting a lot of these:

Other people don't seem to be seeing this.
Is this a make bootstrap?

Weird. Dunno then, sorry.

Not sure what this means.  Is this a "make bootstrap", or is it
something close yet different?

> Wrote c:/Devel/emacs/repo/trunk/lisp/calendar/cal-loaddefs.el

Of course, these may be due to simple "infinite recursion" problems
fixed by bootstrapping.  But they may also be due to "deep recursion",
in which case increasing max-lisp-eval-depth might help (IIRC I had to
bump this limit when I introduced eager macro-expansion, so it wouldn't
be a big surprise if it needs to be bumped yet a bit higher).

The eager macroexpansion can cause fairly deep recursion, especially
if/when some of the code (e.g. macroexp.el) is not yet byte-compiled.
It shouldn't be deeper than the macroexpansion done by the byte-compiler
(it's basically the exact same macroexpansion in both cases), but
because it happens earlier it's suffers more often of things like
"macroexp.el is not yet byte-compiled".

These macroexpansion failures should only be warnings, so do
they prevent building Emacs?

If you can reproduce them, can you try to bump max-lisp-eval-depth a bit
higher to see if it solves the problem?

No, I said "I just bootstrapped (or in fact, build at all) after two
weeks" because it was the first time in two weeks that I was able to
build, because of the pkg-config changes. revno:117116 magically
restored my ability to build. But it was a normal bootstrap.

No.

I'll try and report back.

I experimented with different settings of  max-lisp-eval-depth. I just
changed the default directly in "init_eval_once" in eval.c and
bootstrapped.

With the current value 600 there are hundreds of these warnings.
With 750 there are a few dozen.
With 800 there are none.

I see these failures building current Emacs-git master on MSYS2-MINGW64, 
but if I remove the .git directory from the git cloned tree (*), the 
failures are absent.

Ciao,
 Angelo.

Do the problems go away if you enlarge the value of
max-lisp-eval-depth passed to Emacs during the build?

I have tried the same value suggested in 
http://debbugs.gnu.org/cgi/bugreport.cgi?bug=17517 (message #23), i.e.

  max_lisp_eval_depth = 800

and the failures are removed.

So perhaps it's time for enlarging that value.
