Steve -

That's correct.  If 3.7 could *require* GD 2.x and FT 2.x, then a lot of things could be simplified.

Ok, so where are we at? MapServer and GD are cool. Nothing needs to be
done. Eexcept ditching old versions of GD and Freetype from the
MapServer. Doing so would alleviate some of these issues, expecially the
way Linux comes stocked...

Thanks for your work on this!

OK, it's fixed now.  I was wrong to blame GD.  It was a FreeType bug.

Do NOT use FreeType 2.1.2.  Use FreeType 2.1.3, in which this bug is
documented and fixed.  If you think you have FreeType 2.1.2 and don't
see this problem, keep reading.

I took the test program I sent around and had Steve Woodbridge build it
on his Linux system.  The text went the OTHER way and behaved as
documented.  So we had a little chat:

E: "Are you SURE you're using GD 2.0.11?"
S: "Yup."
E: "Are you SURE you're using FreeType 2.1.2?"
S: "Yup."
E: "Hmmmm...."

A little later, Steve reports that he's running (on Red Hat) RH's
freetype-2.1.2-7 distribution.  Not all FreeType 2.1.2s are alike.  Red
Hat (at least) seems to roll updates and fixes into the RPM, keeping the
same base version.  So Steve's FreeType 2.1.2 was not the same as MY
FreeType 2.1.2 and his had the bug fixed and mine did not.

It appears that other folks are using "newer" FreeType 2.1.2 releases
than mine, explaining why I'm out in this parallel universe seeing bugs
no one else sees.

FreeType 2.1.3 is a stable, full release, and is the current stable
release of FreeType.  Anyone using FT 2 should be using it.
