[Bug 1855993] Re: FTBFS in focal blocking gpsd transition for libgps25

[Christian Ehrhardt ]

navit actually just naively includes <gtk/gtk.h> and the error pups up
much below that.

It has #define GDK_ENABLE_BROKEN might that be related?

Build dep is:
  libgtk2.0-dev
Which brings in:
 libpango1.0-dev | 1.44.7-1           | focal           | amd64, arm64, armhf, i386, ppc64el, s390x

And that has the failing include:
grep -Hn hb.h /usr/include/pango-1.0/pango/pango-coverage.h
/usr/include/pango-1.0/pango/pango-coverage.h:28:#include <hb.h>

The only occurrence of that is in:
$ apt-file search 'hb.h' | grep -e '/hb\.h$'
libharfbuzz-dev: /usr/include/harfbuzz/hb.h
thunderbird-dev: /usr/include/thunderbird/harfbuzz/hb.h

Odd, did it really want that one ...?

  These are from no change rebuilds needed for libgps25, but something
  else made them break.
