The intent is that the 'control-border style for `editor-canvas%' gives
it a border like a control. The default mode is suitable for an editor

Canvas border styles didn't work on Gtk when the canvas has a scroll

I've changed `scribble' to report undefined cross-reference targets to

The "HTML" and "PDF" buttons in DrRacket do not show the warnings,
because those buttons run `scribble' with the `--quiet' flag. I think
Robby has been considering a different implementation of the buttons.
I think I have a repair for the bug, but I'm still checking.

I'll push a repair soon (after I confirm that a clean build now
completes for me).
There were two problems:

since it contains an image constant.

Long answer: At one point, I changed GDK_POINTER_MOTION_MASK to
GDK_POINTER_MOTION_HINT_MASK. My impression from the documentation and
from trying it out was that it generated helpfully fewer mouse-movement

I've pushed a change to Racket's macro system that throws out the

Syntax taints, like syntax certificates before, are intended to
protect macro expansions from abuse. "Abuse" means using
`local-expand' to extract a piece of an expansion, t
I am too buried in syntax-certificate work at the moment to follow

You also mentioned disallowing improper lists as a related change,
which could be significant.
I'd much rather leave this alone and
I like the current order of `take' because it's consistent with
Racket's dominant convention. To the list of advantages, I would add
"consistent with `take' in SRFI-1".
It seems strange to make `take' less compatible with SRFI-1's `take'
toward the end of making `take' be more compatible with SRFI

If you run this program in Racket,
(let ([restart void])
(letrec ([forward-reference (lambda () maybe-ready)] ; affects compiler

[dummy2 (displayln maybe-ready)]

I've pushed a fix to the git repo.
Thanks for the report!

The real `_cprocedure*' (which appears in the expansion of `_fun') has
9 arguments, so something is out of sync.
Do you have a "collects/ffi/compiled/drracket" directory (which should
not exist, but might have been created incorrectly)?

I think so, though it's possible that I've gotten lost in the different
variants of the problem.

I think it's a bad idea to extend the SRFI modules with new functions.
Would it make sense to move functionality from SRFI-19 into
`racket/date' and then add the new functions there (and maybe change
the SRFI-19 implementation to re-export part of `racket/date')?

I couldn't resist an editing pass to give the bullets a more consistent
style.
Matthias: I re-wrote your universe bullet in an attempt to clarify that
the universe API didn't change --- only the network protocol, if I
understand correctly. Please check.

I've pushed fixes for kFreeBSD, so let me know if you encounter further
problems.

I think I'm asking the wrong question. I should instead ask:
What does the man page for fpsetmask() say should be #included?
(The switch to #include was based on a FreeBSD man page.)

Does that avoid the bus error that you saw before?
