So, they're in the DLL itself, but for some reason not marked as exports
in the DEF file, and hence no available stubs for them in the import .a
library.
A simple workaround might be to build with --disable-shared
--enable-static instead.

The DEF file is generated at this point in your make.out log:
generating symbol list for `libpangowin32-1.0.la'

mv -f ".libs/libpangowin32-1.0.expT" ".libs/libpangowin32-1.0.exp"
if test "x`/bin/sed 1q .libs/libpangowin32-1.0.exp`" = xEXPORTS; then cp

Creating library file: .libs/libpangowin32-1.0.dll.a
You could take a look in the .libs/libpangowin32-1.0.exp; probably it
doesn't contain anything that isn't also in
.libs/cygpangowin32-1.0-0.dll.def, but it would be intersteing if it didn't.
And it might be interesting to compare the nm output from those .o files
before and after it gets passed through that sed|sort|uniq pipeline.
Also, you should check that nothing went wrong at configure time that
caused it to disable font support in the built code - maybe it couldn't find
a dependency it needed.
Hmmm. There's various pango and pang-devel packages in the distro. Do
you have any/all/none of those installed? Is this a source build from the
distro source tarballs, or are you trying the upstream sources?
cheers,
