PTRACE_GETSIGINFO is not specific to PowerPC.  It's
architecture-independent (although somewhat recent); IA-64 uses it
for watchpoints just like PowerPC does.  If your system headers are
not new enough to define it, the definition from ppc-linux-nat.c
should probably move to linux-nat.c too.

If that doesn't help, could you show me the error message?  Thanks.
