英文:
"dereferencing type-punned pointer" error when compiling Go 1.4.2
问题
我正在Windows上使用MinGW从源代码编译Go语言。在运行make.bat时，我遇到了以下错误：
# Building C bootstrap tool.
cmd/dist
cmd/dist/windows.c: 在函数 `errstr` 中：
cmd/dist/windows.c:119: 警告：解引用类型转换的指针将违反严格别名规则
我对在Windows上编译不是很有经验，而且似乎这个问题并不常见，因为谷歌没有返回与Go语言相关的特定结果。
编辑1：诚然，这只是一个警告，而不是错误。然而，代码中的检查 if errorlevel 1 goto fail 似乎将这个输出视为错误，并停止了脚本的进程。
英文:
I'm compiling Go from source on Windows with MinGW. When running make.bat, I get the following error:
# Building C bootstrap tool.
cmd/dist
cmd/dist/windows.c: In function `errstr`:
cmd/dist/windows.c:119: warning: deferencing type-punned pointer will break strict-aliasing rules
I'm not very experienced with compiling on Windows, and it appears like this issue isn't very common, as Google doesn't return anything for it specific to Go.
Edit 1: Admittedly this is a warning, not an error. However a check in the code if errorlevel 1 goto fail appears to consider this output an error, and stops the progress of the script.

Go for Windows使用TDM-GCC，这是一个基于GNU工具链的用于32位和64位Windows的编译器套件。
例如，
C:\>gcc --version
gcc (tdm64-1) 4.9.2
英文:
Go for Windows uses TDM-GCC, a compiler suite for 32- and 64-bit Windows based on the GNU toolchain.
For example,
C:\>gcc --version
gcc (tdm64-1) 4.9.2
