Comment 1 Alexey Voinov 2003-08-31 23:11:17 MSD 
на самом деле в autoconf всё совсем запущено :(
большинство тестов с -Wall -Werror не работают.
Я по мере своих сил попробую поисправлять,
но моих сил может и не хватить.

патч для AC_C_CONST

этот патч исправляет один тест. у меня аналогичная проблема
обнаружилась ещё на двух тестах: AC_HEADER_STDC и AC_CHECK_DECLS.
Наверняка есть и ещё, но я пока не вижу.
