* libc/include/sys/lock.h: Add void cast to avoid "statement has no
effect" warnings from gcc.
* libc/include/sys/stdio.h: Ditto.
* libc/include/sys/time.h: Correct gettimeofday() prototype.
* libc/stdlib/__exp10.c: Add #include "std.h" for function prototype.
* libc/stdlib/__ten_mu.c: Ditto.
* libc/stdlib/std.h: Correct __exp10's ANSI prototype.
* libc/stdlib/ldtoa.c: Change eiisinf definition to ANSI form. (Are
already others in file without _ansi method, so did not bother.)
* libc/stdlib/system.c: Use _ansi forms for function prototypes and
definitions.
* libc/time/mktime.c: Ditto.
* libc/misc/__dprintf.c: Ditto.
* libc/include/stdio.h: Add function prototypes for _fgetc_r,
_fgetpos_r, _fsetpos_r, _freopen_r, _rewind_r, freopen64, _freopen64_r,
_funopen_r, and _fopencookie_r.
* libc/include/reent.h: Add function prototype for _stat64_r, align
_execve_r prototype with POSIX definition for execve.
* libc/reent/execr.c: Align function prototype with POSIX definition.
* libc/stdio/asniprintf.c: Add #include "local.h".
* libc/stdio/vasniprintf.c: Ditto.
* libc/stdio/fread.c: Remove unused variable newcount.
* libc/stdio/local.h: Add function prototype for __sccl.
* libc/stdio/open_memstream.c: Remove unused variable flags.
* libc/stdio/vfscanf.c: Proper prototyping for ccfn, remove prototype
for __sccl since now in local.h.
* libc/string/memcpy.c: Add #include <string.h> (for real and for
traditional synopsis), remove extraneous stddef.h and limits.h.
* libc/syscalls/sysclose.c: Add #include <unistd.h>.
* libc/syscalls/sysfork.c: Ditto.
* libc/syscalls/sysgetpid.c: Ditto.
* libc/syscalls/sysexecve.c: Add #include <unistd.h>, align function
prototype with POSIX definition.
* libc/syscalls/sysfstat.c: Add #include <sys/stat.h>.
* libc/syscalls/sysgettod.c: Correct sys/times.h to sys/time.h.
* libc/syscalls/syskill.c: Add #include <signal.h>.
* libc/syscalls/syslink.c: Add #include <unistd.h>, fix prototype.
* libc/syscalls/sysunlink.c: Ditto.
* libc/syscalls/sysstat.c: Add #include <sys/stat.h>, fix prototype.
* libc/syscalls/syswait.c: Add #include <sys/wait.h>, fix prototype.
