Alexander Barton reported a compiler warning on 64-bit platforms: cc1: warnings being treated as errors conn-ssl.c: In function 'ConnSSL_Init_SSL': conn-ssl.c:403: error: cast to pointer from integer of different size Unfortunately, I couldn't find a real solution; the GNUTLS API expects 'gnutls_transport_ptr_t' (which is void*), but the default push/pull functions (send/recv) expect an int. The only alternative solution is to pass in an address to the file descriptor, then add send/recv wrappers that expect a pointer. What a mess[tm].

This patch fixes the following warning of GCC (version 4.3.2) in function ForwardLookup(): resolve.c: In function 'ForwardLookup': resolve.c:282: warning: ISO C90 forbids specifying subobject to initialize resolve.c:284: warning: ISO C90 forbids specifying subobject to initialize resolve.c:285: warning: ISO C90 forbids specifying subobject to initialize

This patch fixes the following warning of GCC (version 4.3.2) in function ConnSSL_LogCertInfo() when compiling with GNUTLS support: conn-ssl.c: In function 'ConnSSL_LogCertInfo': conn-ssl.c:542: warning: unused variable 'cred'

Added files that become generated while building Debian GNU/Linux packages of ngIRCd to the .gitignore lists.

This patch - introduces a new server flag "S" to indicate that the server can handle the SERVICE command (on server links), - implements the IRC command "SERVICE" for server-server links, - uses the "SERVICE" command to announce IRC services when a new server connects to it, - and fixes the Send_Message() function to let it send messages to services using a "target mask". If the remote server doesn't indicate that it can handle the "SERVICE" command (it has not set the "S" flag), services are announced as regular users as before.

- new function ngt_UpperStr(). - change Channel_Write() to take command name and error flag. - remove now unneeded function Channel_Notice().

This patch enables ngIRCd to handle IRC services as real services, and not as "fake users": - Set correct client type CLIENT_SERVICE for services, - Change log messages to include correct client type, - PRIVMSG: allow users to send messages to services, - Send services nick names to other servers (as users). Please note that this patch doesn't announce services as services in the network, but as regular users (as before). Only the local server knows of services as services (see LUSERS command, for example). It is up to one of the next patches to fix this and to introduce the SERVICE command in server to server communication. The propagation of services as regular users between servers doesn't limit the functionality of the IRC services and will be the fallback for servers that don't support "real" services propagation in the future.

Client_TypeText() is used to get correct naming ("Client", "Service", ...) for log messages, and Destroy_UserOrService() is used to correctly destroy user and services clients.

Introduce a new configuration variable "ServiceMask" in SERVER blocks to define a mask matching nick names that should be treated as services. Regular servers don't need this parameter (leave it empty, the default), but you should set it to "*Serv" when connection ircservices, for example. This patch allows ngIRCd to detect services, it doesn't change the functionality: you only get different log messages ;-)
