mkostemp: fix implementation mkostemp(char *template, int flags) generates a unique temporary filename from a template. The flags parameter accepts three of the same flags as open(2): O_APPEND, O_CLOEXEC, and O_SYNC. The current implementation of mkostemp(3) does not respect the flags and in fact confuses the flags with the file mode which should always be S_IRUSR | S_IWUSR. This patch corrects this issue.

stdio: Fix printing 0.0 We were relying on FE_DIVBYZERO being turned off when printing "%f", +-.0 Avoid the whole issue by looking at the sign-bit (in a rough approximation). Note that we do not handle gracefully: printf ("\n%llf\n", -0.0); printf ("\n%llf\n", 0.0); nor %Lf for both when NOT cast to long double. Avoiding an FPE due to broken numbers like these does not make sense to me. Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>

statfs: fix compile error when UCLIBC_LINUX_SPECIFIC is not set statfs() is a Linux-specific function. When building without UCLIBC_LINUX_SPECIFIC set, libc_hidden_proto(statfs) in include/sys/statfs.h is unmatched with libc_hidden_def(statfs) in libc/sysdeps/linux/common/statfs.c, leading to a compile error. This patch fixes this, as well as adds statfs() to the list of Linux-specific functions in extra/Configs/Config.in. Signed-off-by: Anthony G.
