[BZ #2908]
* stdio-common/printf_fphex.c (__printf_fphex): When rounding up 'f', use '1' as leading digit not '\1'. * stdio-common/Makefile (tests): Add bug16. * stdio-common/bug16.c: New file. [BZ #2914] * sysdeps/unix/sysv/linux/gethostid.c: Don't define OLD_HOSTIDFILE and don't try to open it. The patch introducing the macro contained a bug and used the same file name as the new file instead of using /var/adm/hostid. Nobody complaint so I'm taking this out completely. [BZ #2926] * assert/assert.h: Move cast to void inside ?: to quiet gcc. Patch by Jerry James <Jerry.James@usu.edu>.
