修正交叉编译mingw32-gcc-base时找不到头文件的错误

Loaden

主要原因是--with-headers参数不好使，不知道为什么，用GCC 4.4.3编译官方的PKGBUILD时失败：找不到windows.h。

改了一下PKGBUILD文件，现在可以编译了。

一共改了两个地方，首先将头文件路径改一下：

1.   # prepare headers
2.   mkdir -p $srcdir/mingw/include/
3.   cp -r $srcdir/w32api-${_w32apiver}-mingw32/include/* \
4.     $srcdir/mingwrt-${_runtimever}-mingw32/include/* \
5.     $srcdir/mingw/include/

复制代码

其次，将配置参数改一下：

1. --with-sysroot=$srcdir \
