* stdio-common/Makefile (tests): Add bug10.
* stdio-common/bug10.c: New file. From HJ Lu.
* stdio-common/tstdiomisc.c: Make more test-suite like: exit
status tells about successful run.
* stdio-common/vfscanf.c [!USE_IN_LIBIO]: Use `flags' to check
format correctness.
Correct handling of trailing white spaces in format + EOF.
Fri Dec 15 01:31:56 1995 Ulrich Drepper <drepper@gnu.ai.mit.edu>
* stdio-common/Makefile (tests): Add bug8 and bug9.
* stdio-common/bug8.c, stdio-common/bug9.c: New tests.
* stdio-common/vfscanf.c: Fix bug in dynamic buffer handling.
* stdlib/strtod.c: Correct spelling: nominator -> numerator.
Thanks to Jim Meyering.
Sat Nov 25 06:05:12 1995 H.J. Lu <hjl@nynexst.com>
* stdio-common/vfscanf.c: Always check width !=0.
Correctly handle %%.
