glib2 собирается libtool'ом, скрипт для экспорта символов
генерируется автоматически:

$ pwd
/home/at/RPM/BUILD/glib-2.8.1/glib
$ head .libs/libglib-2.0.ver
{ global:
IA__g_access;
IA__g_allocator_free;
IA__g_allocator_new;
IA__g_array_append_vals;
IA__g_array_free;
IA__g_array_insert_vals;
IA__g_array_new;
IA__g_array_prepend_vals;
IA__g_array_remove_index;
$

Некоторые символы я хочу перевесить на отдельный интерфейс.
Для этого я делаю другой скрипт на основе этого *.ver скрипта.

Затем подменяю в Makefile'е экспорт символов:

Ошибка:

Внимание, вопрос: позволяет ли version script одновременно ограничить
список экспортируемых символов (для дефелотного интерфейса, то есть без
интерфейса) и одновременно перевесить некоторые функции на отдельный
интерфейс?

И ещё вопрос: что это за IA__ символы, зачем их экспортировать?
