作为源代码的开发者，有很多关于如何禁用GCC警告的冗余解释。现在，我想知道是否有一种方法可以在不触及源代码的情况下禁用它们（包括构建工具配置文件），即让编译继续忽略警告.在我对GCC文档的理解中，在 * Options to Request or Suppress Warnings *，如果为./configure和make指定了CXXFLAGS="-w"，则CXXFLAGS="-w"就足够了，例如CXXFLAGS="-w" ./configure && make。
备注：我知道违背开发者的意图编译程序不是一个好主意，沟通问题并一起修复它总是更好的选择，如果不是唯一的选择。
背景（请阅读整个问题，尤其是上面和下面的备注，我不是在寻找解决以下问题的方法！）：我尝试在Synology DSM 5.0上使用armv7架构在Debian 7.6 chroot中编译QEMU Git tag v2.1.0，并获得

我尝试了一些选项，现在我只想知道是否有可能在GNU构建工具中获得更好的结果。我非常确定构建结果即使不是不可用的，至少也是不可靠的。
顺便说一句：如果你通过搜索引擎找到了这个问题，并且在QEMU上遇到了同样或类似的问题，请参见 * Build of v2.1.0 fails on armv7l due to undeclared __NR_select *。
