[Linux-ia64] sscanf() broken on ia64

Hi,

I'm having a problem with sscanf() on IA-64; it seems to be able to parse
a string into arguments correctly when whitespace is the delimiter, but
not "."!

Below is a small module to illustrate what I mean (you must be running
2.4.10 or greater, since that's when sscanf was added).  On IA-64 I get

sscanf returned 1, d1=192, d2=0, d3=30, d4=0, port=0
sscanf returned 5, d1=192, d2=1, d3=1, d4=132, port=80

when I should get the latter both times (as I do on x86).

Can someone help?

Thanks,

David
