request for help regarding a bidi patch

[Omer Zak]

In Debian Lenny, the libpango version (libpango1.0-0) is 1.20.5-5+lenny1
In this version, /usr/include/pango-1.0/pango/pango-types.h declares the
functions which you need.

Outputs requested by you:
$ objdump --dynamic-syms /usr/lib/libpango*.so  | grep base_dir
00016500 g    DF .text  00000130  Base
pango_itemize_with_base_dir
00028a20 g    DF .text  000000a6  Base        pango_find_base_dir
00015060 g    DF .text  00000050  Base        pango_context_set_base_dir
00015000 g    DF .text  00000052  Base        pango_context_get_base_dir

$ objdump --dynamic-syms /usr/lib/libpango*.so  | grep unichar_direction
000289e0 g    DF .text  00000034  Base        pango_unichar_direction

I have also a directory with files from RedHat 8.0, where the pango
version is 1.1.1 (from August 2002).  In this version, the functions
which you need don't exist.

>From modern pango changelog.gz:
Overview of changes between 1.3.3 and 1.3.5
===========================================
* Add support for automatically determining the base direction for
  PangoLayout from the contained text [Dov Grobgeld]

So the first supporting version is probably somewhere between 1.3.5 and
1.20.5-4 (inclusive).

                                          --- Omer
