Hi,

While cross-compiling glibc-2.2.5 for target=cris-linux using gcc-3.1 and
binutils-2.12.90.0.7, I get an error

cris-linux-gcc cancel.c -c -O2 -Wall -Winline -Wstrict-prototypes -Wwrite-strings -g   -D__NO_WEAK_PTHREAD_ALIASES -D_RPC_THREAD_SAFE_   -I../include -I. -I/backup/cross-build/build-glibc-cris/linuxthreads -I.. -I../libio  -I/backup/cross-build/build-glibc-cris -I../sysdeps/cris/elf -I../linuxthreads/sysdeps/unix/sysv/linux -I../linuxthreads/sysdeps/pthread -I../sysdeps/pthread -I../linuxthreads/sysdeps/unix/sysv -I../linuxthreads/sysdeps/unix -I../linuxthreads/sysdeps/cris -I../sysdeps/unix/sysv/linux/cris -I../sysdeps/unix/sysv/linux -I../sysdeps/gnu -I../sysdeps/unix/common -I../sysdeps/unix/mman -I../sysdeps/unix/inet -I../sysdeps/unix/sysv -I../sysdeps/unix -I../sysdeps/posix -I../sysdeps/cris -I../sysdeps/wordsize-32 -I../sysdeps/ieee754/flt-32 -I../sysdeps/ieee754/dbl-64 -I../sysdeps/ieee754 -I../sysdeps/generic/elf -I../sysdeps/generic  -nostdinc -isystem /cross/cris-linux-tools/lib/gcc-lib/cris-linux/3.1/include -isystem /cross/cris-linux/include -D_LIBC_REENTRANT -include ../include/libc-symbols.h     -o /backup/cross-build/build-glibc-cris/linuxthreads/cancel.o

make[2]: *** [/backup/cross-build/build-glibc-cris/linuxthreads/cancel.o] Fehler 1

The fix is to add a file sysdeps/cris/stackinfo.h.

	* sysdeps/cris/stackinfo.h: New file.
