* stdio-common/vfscanf.c: Major change. Now read character from stream only if needed. Before it was read after the previous character was used. Bug reported by Martin Goik <goma0002@FH-Karlsruhe.DE> * stdio-common/tstscanf.c: Change test program so that return value is != 0 if one test failed. * sysdeps/m68k/Makefile (crypt): Variable removed. * sysdeps/sparc/Makefile: Likewise.
