glibc-2.3.3-alpha-pwrite64.patch

在linux下建立交叉编译环境的she

Attempted fix for this error:

wget 'http://sources.redhat.com/cgi-bin/cvsweb.cgi/libc/sysdeps/unix/sysv/linux/alpha/sysdep.h.diff?r1=1.16&r2=1.17&cvsroot=glibc'
and rediffed.

cf.

Originally thought we needed this hunk, too:
http://sources.redhat.com/ml/libc-alpha/2003-10/msg00037.html
but it seems the sysdep.h change is sufficient, and works better 
when compiling against linux-2.4.

And then rediffed again against glibc-2.3.3
