[reSIProcate] Compiler error in TcpBaseTransport

[Dario Bozzali]

Hi all,

I've got head revision of Resiprocate and I tried to compile.

I encountered the following compiler errors (my environment is Visual
C++ 2005) since size of _sa is not constant.

 

1>.\TcpBaseTransport.cxx(219) : error C2057: expected constant
expression

1>.\TcpBaseTransport.cxx(219) : error C2466: cannot allocate an array of
constant size 0

1>.\TcpBaseTransport.cxx(219) : error C2133: '_sa' : unknown size

 

I would suggest a change to the code similar to the one that I reported
below. Or _sa could have the size equal to MAX(sizeof(sockaddr_in),
sizeof(sockaddr_in6)).

Thank you in advance and kind regards,

Dario.
