warning fixes

[Andreas Jaeger]

I've commited the appended patches to silence these valid GCC
warnings:

regex.c:2728: warning: operation on `idx' may be undefined
../sysdeps/generic/dl-cache.c:187: warning: assignment from incompatible pointer type

	* posix/regex.c (regex_compile): Change to get defined behaviour.

	* sysdeps/generic/dl-cache.c (_dl_load_cache_lookup): Change to
	avoid warning.
