[Cpptool-develop] Fixes for VS6 compilation...

[Andre B. <and...@gm...>]

hello baptiste,

A few fixes for compiling the code under VC6:

- the code is compilable with "v3" of regexpr.
- one additional problem is the type "std::size_t" which is not defined 
that way in VC6
   When using "size_t" instead, the code is fully compilable.
- the files "symboltabletestprocessor" were not in the project ... is fixed.
- with this all tests run through only one failes:
     Testing 'All Tests/SymbolTableTest/variable1.txt' : ASSERTION
     don't know how to check node type: variable
     At line: 5, column: 1
     Failures: 1, Tested: 182
   "I think you expected this ;-)"

I'm going through the code...

greetings,
André
