 I would probably use something like

MOREXLIBS="-L/usr/local/lib -lwine -L/usr/X11R6/lib -lSM -lICE -lXpm -lXxf86dga -lXxf86vm -lXext -lX11 -lncurses -lm -ldl"
AC_CHECK_LIB(wine, MAIN_WinelibInit,[$MOREXLIBS])

 but this wouldn't be very portable (ncurses, math lib).

 You have to put in tests for every single library and -L path you need
 to use before testing for the wine lib. You definitely want to use
 AC_PATH_XTRA for the X stuff, like:

AC_PATH_XTRA
if test "$no_x" != yes; then
  CPPFLAGS="$CPPFLAGS $X_CFLAGS"
  LIBRARIES_FOR_X="$X_LIBS -lX11 $X_EXTRA_LIBS"
  AC_DEFINE(X11, 1,
            [ Define if you are using the X11 window system. ])
