Questions about socket programming

[Hubert <herrdoktor@fumanchu.com>]

Hello,

I want to write a small telnet server as an exercise and also because I 
need this functionality elsewhere. I seem to remember that I read in 
this newsgroup somewhere some negative opinions about Gnatsockets, but I 
can't remember where and what it was about.
So I wonder, should I use Gnatsocket or are there any problems? Should I 
rather interface with C and use the C socket implementation directly? I 
must admit that I tried this today and didn't get very far, because I 
got linker errors like these:

Berkley_Socket_Interface_C.c:47: undefined reference to 
`_imp__getaddrinfo@16'

Berkley_Socket_Interface_C.c:48: undefined reference to `gai_strerrorA'

Berkley_Socket_Interface_C.c:49: undefined reference to `_imp__WSACleanup@0'

collect2.exe: error: ld returned 1 exit status


and I am out of ideas there. I tried to add to the C linker the 
following switches:

-lwsock32 -lws2_32

but without luck. I found contradictory information what the correct 
library name is for mingw, so I tried both but apparantly both are 
wrong, or the respective libraries are not delivered with Adacore Libre.
I should had that I don't have Mingw installed, just what comes with 
Adacore.

Thanks for any help
