Update.
2000-12-13 Jakub Jelinek <jakub@redhat.com> * misc/efgcvt.c (FCVT_MAXDIG): Define. (FCVT_BUFPTR): New variable. (fcvt): If fcvt_r returns -1 on the static short buffer, try to malloc a sufficiently large one and retry. (free_mem): New function. * misc/qefgcvt.c (FCVT_MAXDIG): Define. * misc/tst-efgcvt.c (fcvt_tests): Add new test. 2000-12-15 Ulrich Drepper <drepper@redhat.com> * misc/dirname.c (dirname): Fix search for second to last slash. 2000-12-13 Andreas Jaeger <aj@suse.de> * misc/tst-dirname.c (main): Fix typo in test to really use the examples from Unix98. Reported by Michael Kerrisk <mtk16@ext.canterbury.ac.nz>.
