Has anyone else had trouble with the
appkit include files that use protocols?
I've got an application that includes
/NextDeveloper/Headers/appkit/drag.h and
it's giving me these errors:

tumbleweed# make tst
cc   tst.c  -o tst
/NextDeveloper/Headers/appkit/drag.h:47: illegal keyword selector, missing `)'
after `id'
/NextDeveloper/Headers/appkit/drag.h:48: illegal keyword selector, missing `)'
after `id'
/NextDeveloper/Headers/appkit/drag.h:49: illegal keyword selector, missing `)'
after `id'
/NextDeveloper/Headers/appkit/drag.h:50: illegal keyword selector, missing `)'
after `id'
/NextDeveloper/Headers/appkit/drag.h:51: illegal keyword selector, missing `)'
after `id'
/NextDeveloper/Headers/appkit/drag.h:52: illegal keyword selector, missing `)'
after `id'
*** Exit 1
Stop.

Each of these lines in the header file identifies
a protocol method.

What gives?  Any ideas?

The problem is that your filename ends in ".c", not ".m". The compiler
looks at that and says "This is C code, not Objective-C code" and
complains when it hits something that is Objective-C specific.

The two solutions are to either use ".m" as your extension or to compile
with the -ObjC switch. (Which also tells the compiler to treat the file
as Objective-C) Either technique will work.

mv tst.c tst.m # should fix it

you can also change some CFLAG in your Makefile preamble but I forgot
what its called.

What's happening here is that you've got Objective-C syntax in a regular C  
code file, so the compiler is complaining.
There are two possible solutions.
1.  rename your file tst.c to tst.m  -- the ".m" extension  tells the  
compiler that you will be compiling Objective-C code.  The ".c" extension  
says that the file just contains C.

- OR -

2.  Compile with a "-ObjC" flag.  This explicitly tells the compiler to  
expect Objective C syntax in the file.
	> cc -ObjC tst.c -o tst
