Sorry,
ping is not in net-tools, but in netkit... I have debian
gcc version egcs-2.91.63 19990224 (egcs-1.1.2 pre-release-3) handy
and ping compiled `gcc -o ping ping.c' works, but product of
`gcc -o ping -O ping.c' does not work :-(

Hi,
problem is in ping. Ping from (debian) netbase-3.11-1.2 (net-tools 1.45)
works, but from netbase-3.14-1 (net-tools 1.51) does not. But problem
is not in ping program version, but in compiler. I have ping from
net-tools 1.45 compiled on one machine using gcc-2.8.1 and it does not
work. Same code compiled 2.7.2.3 does :-( And packet is odd-sized
on media (ping -s 91 produced 137 bytes long ethernet frame
with checksum 0x15A4 instead of 0x15FD; btw, last character from frame
is 0x5A;; packets from gcc-2.7.2.3 ping are also 137 bytes long,
but correctly checksummed *). So kernel has nothing to do with it...
Best regards,
Petr Vandrovec

P.S.: Grr :-( I have to reinstall gcc-2.7.2.3 on my machine (or check
egcs-1.1.2).
