Description:
GCC 4.6 (unreleased) added a new warning option (-Wunused-but-set-variable, activated by -Wall) that causes quite a few warnings in innodb code:

btr/btr0pcur.c: In function 'btr_pcur_move_backward_from_page':
btr/btr0pcur.c:432:8: warning: variable 'space' set but not used [-Wunused-but-set-variable]
btr/btr0sea.c: In function 'btr_search_update_hash_on_delete':
btr/btr0sea.c:1404:8: warning: variable 'found' set but not used [-Wunused-but-set-variable]
buf/buf0flu.c: In function 'buf_flush_batch':
buf/buf0flu.c:844:8: warning: variable 'old_page_count' set but not used [-Wunused-but-set-variable]
[..]

How to repeat:
Use gcc 4.6 and compile with -Wall -Wunused
