[Nagiosplug-devel] check_tcp on solaris

[hans hm04]

hi all 

the following problem exists on solaris with check_tcp:
we receive signal 11, if the tcp-connection to a given
port could not be established. so the signal must be catched, 
otherwise we die ungracefully with exit status 139 and 
core-dump. 

i don't know, who is the maintainer, but could you be so kind
and apply with patch the following modifications 
to files "configure" an "check_tcp.c" 

best regards 
hans
