	* stdlib/strtod.c (STRTOF): Skip whole infinity, not just inf.
	* stdio-common/vfscanf.c (__vfscanf): +- can be followed by i in +-Inf.

	* stdlib/tst-strtod.c (tests): Add Inf tests.
	* stdio-common/tstscanf.c (main): Add tests for +- before Inf.

	* locale/weightwc.h (findidx): Change type of i to int32_t.
