在ubuntu上编译toolchain时出错./stdio.h:477: error: 'gets' un

注：验证通过。

原因：

/* It is very rare that the developer ever has full control of stdin,

so any use of gets warrants an unconditional warning.  Assume it is

always declared, since it is required by C89.  */

#undef gets

_GL_WARN_ON_USE (gets, "gets is a security hole - use fgets instead");

解决方案：

build/host-m4-1.4.16/lib$ sed -i -e '/gets is a security/d' ./stdio.in.h

将“_GL_WARN_ON_USE (gets, "gets is a security hole - use fgets instead");”一行删除，即可编译通过。
