sysdep-cancel-arm-1.2-1.6.patch

linux下编译交叉工具链的工具源码

I haven't built glibc-2.3.2 for arm myself, but
http://sources.redhat.com/ml/bug-glibc/2003-05/msg00076.html and
http://www.linux.org.uk/pipermail/linux-arm/2003-November/006560.html
give me the distinct impression that you need the latest sysdep-cancel.h from
cvs.
