It should compile. Try to compile the code as C++ code (change the file 
extension to .cpp or change compiler settings)

In the attachment you'll find a Visual Studio 08 solution to create a 
simple C parser based on the following C grammar:
http://www.lysator.liu.se/c/ANSI-C-grammar-y.html
it checks the syntax of test.c. Inside the zip you'll find also a batch 
(rename it form .eee to .bat to bypass gmail checks) to run bison and 
flex from cygwin distribution.

I think this is a good starting point:

Also this link could be useful for you, if you love to use Visual Studio:

You can download the rules from:

As a general rules using bison:

  1. Install flex and bison from cygwin (or download from
     http://gnuwin32.sourceforge.net/packages.html)
  2. Open MS Visual Studio and create *Win32 Console Application project.*
  3. Open Project/ Project Property Pages/Configuration
     properties/C/C++/Precompiled Headers and chose *Not Using
     Precompiled Headers*.
  4.   In Project Defaults chose *Use Multi-Byte Character Set*
  5. Add in "additional include directory" unistd.h, provided with bison


Bye,
