string2-typedef.patch

linux下编译交叉工具链的工具源码

See http://gcc.gnu.org/ml/gcc/2003-08/msg00959.html

Compiling glibc-2.3.2 with a gcc-3.4 snapshot, I'm seeing
a whole bunch of warnings like this:

../string/bits/string2.h:80: warning: `packed' attribute ignored
../string/bits/string2.h:81: warning: `packed' attribute ignored
...

Looks like it was bad code that was silently ignored by previous compilers.
Ulrich fixed it as follows:
