here are the errors on the two (unfortunately 

one compiles on yours)

and i deleted TCL_HAVE_THREADS from

 the list of cc defines as it broke 2 others (

and didnt fix these two) (tclUnixSock.c, 

tclIOSock.c)

/C

ps. addrinfo is mentioned in the configure script and writes to tclConfig.h.in a flag (i tried turning this on and off)
