  I brought this up several months ago when I first got my NeXT.
I never got a fix, though I did get help for several other 
problems in my post. 

  Has anyone gotton GNUPLOT to compile under 3.0?  I'm having
trouble in the term module. Specifically, some of the NeXTStep
headers (in appkit) with constructs like

    somtheing = (id<NXDraggingInfo>) something else 

refuse to compile. The compiler complains about not being able
to find the ")" after the (id.  Random attemps to trivially change the 
syntax (in hopes that it is only a parser bug), like adding spaces 
do not work. I suspect some knowledge of object oriented c programming
might help. 

 Thanks in advance for any help,

Regards, chuck@pierre.mit.edu

You have given the answer already. The problem is that the objective-C
code is included from a "plain C" program who's filename ends with ".c".
Since NextStep 3.0 (really: since GNU-C 1.whatever) the compiler just
forgets all he knows about objective-c _if_ the source file has the
".c"-Extension. So to provide the compiler with knowledge of object 
oriented c programming" one has to use the correct extension.

Workaround: rename "term.c" (if mind serves...) to "term.m", edit the
Makefile accordingly. (Thanks to Frank Siegert who found this out.)

Best regards,

Andreas.
