Update.
2001-08-06 Jakub Jelinek <jakub@redhat.com> * 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.
