Hi!

-Wcast-qual complains about (const void **) htab_find_slot () cast,
fixed thusly, bootstrapped with --enable-checking=yes,fold
- --enable-languages=c on x86-64-linux, committed to trunk as obvious.

2010-09-16  Jakub Jelinek  <jakub@redhat.com>

	PR bootstrap/45686
	* fold-const.c (fold_checksum_tree): Change slot from const void **
	to void **, use CONST_CAST_TREE to store into *slot.


	Jakub
