Javacc assistance: adding a block of arbitrary text

Question

Hi all
I'm developing a statechart compiler, which takes in a textual format and generates C. This C is destined for embedded systems. Part of the frontend of the compiler is my parser.
Most of my parser grammer is done, apart from this: allowing parsing of arbitrary text, as per this example:
MyStateA
  entry
    --arbitrary C code here--
}So, parse the state block, which contains an entry block (all good so far). But how do I approach the arbitrary C code section? I dont want to incorporate the entire C grammer into my langauge. I've seen techniques whereby { and } braces are counted somehow, and the skip and token specs change. In this arbitrary code section, I can make the requirement that there must be prefectly paired braces within, thus the last closing one for entry can be determined.
Can someone give me a hand with this?
Thanks
Rich

Okay, my compiler / code generator is written in Java. Thus the output of javacc plays very well with the rest of the compiler. It is the output of my compiler that is C.
I currently have something like:
void State()
  (Entry())?
void Entry()
  <ENTRY>
  <LEFTBRACE>
    (nothing here yet)
  <RIGHTBRACE>
}What does one do next? Do I define a token for (.*)? Then do something like x=<THAT_TOKEN> in the middle there? At some point I need to capture the actual code to place into my intermediate representation. None of the capturing parts of the input to the IR is done yet.
void Entry()
  <ENTRY>
  <RANGLEBRACE>
    (something)
  <LANGLEBRACE>
}Cheers
