Hi Deri,

afmtodit: both Upsilon and Upsilon1 map to *U at

BuildFoundries: notice: Generated U-S...


This has "always" been there, but about a year ago I made the complaining
program identify itself (3b680c85).  It's ignorable, though I'd like to do
something about it.  I guess we should pick one of these Adobe glyphs for our
*U character--whichever one is more useful for scientific/mathematical use of
Greek, I reckon, and tell users they'll need to get the other via the \N
escape sequence.

I see these all the time.  They're "harmless", like the afmtodit warning, but
I'd like to fix them some day.

pnmcrop: The image is entirely background; there is nothing to crop.


This is bad news.  I don't get these.  Something is going wrong in/around
grohtml.  I expect your copy of the HTML version of the pic manual is missing
all of its images and is therefore nearly useless.  That's a showstopper.  I
broke but then fixed grohtml over the course of a couple of days, though I
don't remember seeing these exact diagnostics.  If you're on a branch
(sboxes?) make sure you have commit 991aa9da (30 July).  But don't get your
hopes up--I suspect you do have it because you're seeing errors from the pnm*
suite, and another change of mine around the same time made these changes
visible (98367a84, 26 July).

These have been a fixture of mom(7) for a long time; we're resigned to telling
people to ignore them.

This looks bad and I'm guessing it has a similar cause as the pic.html
trouble.  Your version of gs (9.53.3) is newer than mine
(9.27).

This reminds me that I still owe you some work in this area.

This is the uchardet issue you noted.  Is it common for libuchardet to be
installed without its pkg-config support in place?  A more traditional
Autoconf test might be useful, I admit.

I didn't see anything else that jumped out at me in config.log, but the file
is huge.  Please call out anything I missed.

Moving on to the test suite log...

==============================

FAIL tmac/tests/s_PN-works.sh (exit status: 1)


Can you have a look at the body of the test and try to reproduce it with
test-groff in your build?  It's really simple and I can't imagine what might
have gone wrong.  This test does not fail on HEAD.


FAIL: src/roff/groff/tests/break_zero-length_output_line_sanely.sh
==================================================================

troff: <standard input>:10: warning [p 0, 0.0i, div 'A', 0.0i]: can't break

FAIL src/roff/groff/tests/break_zero-length_output_line_sanely.sh (exit

This one bears close examination too.  Are you on a branch?  Did you somehow
not get commit 69efbe0a (4 September)?

The bad news(?) is that HEAD is green for me, so I'll need your help to chase
these down.
