" Note:		Splint annotated files are not detected by default.
"		If you want to use this file for highlighting C code,
"		please make sure splint.vim is sourced instead of c.vim,
"		for example by putting
"			/* vim: set filetype=splint : */
"		at the end of your code or something like
"			au! BufRead,BufNewFile *.c	setfiletype splint
"		in your vimrc file or filetype.vim


" For version 5.x: Clear all syntax items
" For version 6.x: Quit when a syntax file was already loaded
if version < 600
  syntax clear
elseif exists("b:current_syntax")
  finish
endif

" Read the C syntax to start with
if version < 600
  so <sfile>:p:h/c.vim
else
  runtime! syntax/c.vim
endif


" FIXME: uses and changes several clusters defined in c.vim
"	so watch for changes there

" TODO: make a little more grammar explicit
"	match flags with hyphen and underscore notation
"	match flag expanded forms
