为交叉编译器构建 newlib 时出现 'gettimeofday' 的类型冲突

Question

在尝试构建 newlib 1.20.0 时...我按照这个教程http://wiki.osdev.org/OS_Specific_Toolchain#newlib.2Flibc.2Fsys.2Fmyos

但是当尝试构建 newlib 时，我收到以下错误:

/../newlib-1.20.0/newlib/libc/sys/myos/'`syscalls.c
../../../../../../newlib-1.20.0/newlib/libc/sys/myos/syscalls.c:29:5: error: conflicting types for 'gettimeofday'
In file included from ../../../../../../newlib-1.20.0/newlib/libc/sys/myos/syscalls.c:7:0:
/usr/src/newlib-1.20.0/newlib/libc/include/sys/time.h:74:5: note: previous declaration of 'gettimeofday' was here
Makefile:280: recipe for target `lib_a-syscalls.o' failed

sycalls.c 用于 gettimeofday 声明:

int gettimeofday(struct timeval *p, struct timezone *z);

时间.h:

int _EXFUN(gettimeofday, (struct timeval *__p, void *__tz));

那么什么是冲突类型？请帮助...任何帮助表示感谢...

更改 syscalls.c 中函数的声明。然后将 void * 转换为结构体时区。
