Re: Solaris and socket library

[Bob Friesenhahn <bfriesen at simple dot dallas dot tx dot us>]

This is an Autoconf issue, not Automake.  Adding the following line to
your configure.ac file will likely resolve the problem:

  AC_SEARCH_LIBS([connect],[socket],[],[],[])

It should add -lsocket to LIBS if necessary.
