[libcvd-members] GVars and motif for macosx

[Pablo Barrera]

Hi

I tried to compile gvars3 in a mac without fltk support, just an old  
fashion motif look-and-feel. I didn't compile out of the box.

$ ./configure --disable-fltk2
...
GUI support:
motif
...

$ make
...
rm -f libGVars3.dylib libGVars3-0.dylib libGVars3-0.6.dylib
g++ -dynamiclib -o libGVars3-0.6.dylib src/gvars3.o src/GUI.o src/ 
GStringUtil.o src/gvars2.o src/GUI_language.o src/serialize.o src/ 
GUI_Motif.o src/GUI_non_readline.o src/inst.o src/GUI_readline.o src/ 
GUI_impl_readline.o -L/usr/X11/lib -lreadline  -L/sw/lib -L/opt/local/ 
lib -pthread -pthread -lXm -lm
Undefined symbols:
  "_XtAppNextEvent", referenced from:
      GVars3::GUI_Motif::DoMotifEvents()     in GUI_Motif.o
      GVars3::GUI_Motif::AddWindow(std::basic_string<char,  
std::char_traits<char>, std::allocator<char> >)in GUI_Motif.o
...

It seems some libraries are missing for X11: -lXt and -lX11.

Just a little change in configure.ac will do the trick.

I suppose this will not break anything else.

PS: With fltk2 compiles fine.
