[PATCH] shut up warnings in bits/string2.h

[Jakub Jelinek <jakub at redhat dot com>]

Hi!

This patch shuts up gcc 2.96 warnings about long switch expressions not
converted to int.
BTW: I've seen pretty bad code as result of the string2.h inlines on sparc,
while -D__NO_STRING_INLINES gave me much better code as the compiler did the
job. I'll investigate why that happens and for which functions and submit a
sparc string.h which will disable those inlines from string2.h which result
in bad code. How does it work on other architectures?

	* string/bits/string2.h (__memset_gc, __mempcpy_small, __strcpy_small,
	__stpcpy_small): Cast switch expressions to int to shut up compiler
	warnings.
