2000-07-27 Jakub Jelinek <jakub@redhat.com> * locale/indigits.h (indigit_value): Correct. * locale/indigitswc.h (indigitwc_value): Correct. * stdio-common/vfscanf.c (__vfscanf): Fix I18N number conversion, add GROUP checking for it, fix GROUP number conversion with strlen(thousands) > 1. Honour width correctly in the presence of floating decimal points and thousands separators. * stdio-common/tst-sscanf.c: New test. * stdio-common/Makefile: Add it to tests. * sysdeps/generic/strtol.c (strtol): Fix conversion if there are thousands separators and group argument is non-zero. Reported by Andi Kleen <ak@suse.de>.
