Apologies about the timing. Submitted for your consideration:

  AC_CHECK_LIB(socket,socket)
+AC_CHECK_LIB(resolv,herror)
  AC_CHECK_LIB(nsl,gethostent)
  AC_CHECK_LIB(dl,dlopen)


Curiously, the autoconf manual's comments on AC_CHECK_LIB seem rather  
close to the mark:
> AC_CHECK_LIB requires some care in usage, and should be avoided in  
> some common cases. Many standard functions like gethostbyname  
> appear the standard C library on some hosts, and in special  
> libraries like nsl on other hosts. On some hosts the special  
> libraries contain variant implementations that you may not want to  
> use. These days it is normally better to use AC_SEARCH_LIBS 
> ([gethostbyname], [nsl]) instead of AC_CHECK_LIB([nsl],  
> [gethostbyname]).
