Allow C static library to be used from C++.

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Make a new proto
2. Compile proto
3. Compile code into a static C library
4. Link to the library from external C++ code.

What is the expected output? What do you see instead?
Should be able to call those functions in C++.  Instead get undefined reference 
errors.  This is due to C++ function mangling.  If the outputed code simply 
included 

extern "C" {
#endif
//
// put C function prototypes here
int somefunction(int);
// other function prototypes here

#ifdef _cplusplus // if compiled with C++ compiler
} // end of extern "C" block
#endif

This would fix the problem.

What version of the product are you using? On what operating system?
1.02M under Cygwin and Linux

Please provide any additional information below.

Please close this issue. I submitted it before I thought.  Simply wrapping the 
#include with extern "C" { } works just fine.

As said in the previous comment this does not need to be fixed.
