I have just finished installing Elm on my 68k unix box running XUnisoft Uniplus+ sysvr1. Unfortunately the C compiler doesn't support Xlong variable names so I had the dubious honor of updating shortnames.h Xto include several new variable and function names. I also do not have Xthe setvbuf() function. I modified filter.h to delete it. I am enclosing Xmy changes if you are interested... X XManlio D.
