2005-08-26  Paul Eggert  <eggert@cs.ucla.edu>
	[BZ #1248]
	* posix/regex_internal.h (bitset_not, bitset_merge, bitset_not_merge,
	bitset_mask, re_string_allocate, re_string_construct,
	re_string_reconstruct, re_string_destruct, re_string_elem_size_at,
	re_string_char_size_at, re_string_wchar_at, re_string_peek_byte_case,
	re_string_fetch_byte_case, re_node_set_alloc, re_node_set_init_1,
	re_node_set_init_2, re_node_set_init_copy, re_node_set_add_intersect,
	re_node_set_init_union, re_node_set_merge, re_node_set_insert,
	re_node_set_insert_last, re_node_set_compare, re_node_set_contains,
	re_node_set_remove_at, re_dfa_add_node, re_acquire_state,
	re_acquire_state_context): Remove unnecessary forward decls.
	(re_string_char_size_at, re_string_wchar_at, re_string_elem_size_at):
	Put __attribute at function definition, now that the function decl
	has been removed.
	* posix/regex_internal.c (re_string_peek_byte_case,
	re_string_fetch_byte_case, re_node_set_compare, re_node_set_contains):
	Likewise.
