Compiling program for old gcc - c++

Question

I have to compile program probcons but there are many errors. In readme autor writes program is compatible with gcc 4.3 but I have only 4.7.2. Is there any way to compile this old program? I don't believe that in program are errors because many bioinformatics servers are using it.
Most odd to me is this error:
Description Resource Path Location Type
expected ‘)’ before ‘size’ SafeVector.h /probcons line 27 C/C++ Problem
expected ‘)’ before ‘size’ SafeVector.h /probcons line 26 C/C++ Problem
In class SafeVector.h:

SafeVector(const SafeVector &source) : std::vector<TYPE>(source) {}
#ifdef ENABLE_CHECKS
// [] array bounds checking
TYPE &operator[](int index){
assert (index >= 0 && index < (int) size());
return std::vector<TYPE>::operator[] ((size_t) index);
}
// [] const array bounds checking
const TYPE &operator[] (int index) const {
assert (index >= 0 && index < (int) size());
return std::vector<TYPE>::operator[] ((size_t) index) ;
}
#endif
};
How it is possible that in older version of gcc wasn't need includes and std::prefix?

Try specifying the language standard for gcc. I suggest you try
-std=c++11
e.g g++ -std=c++11 -o out.exe myfile.cpp
first, I think it is most likely to compile it. If it doesn't work, try other choices.
How to add this depends on how the compilation is done, but one "quick&dirty" way is to add this is to find the makefile, find a line which specifies compiler flags variable CXXFLAGS and add that to it. Note: if it is a generated makefile, edits get overwritten if you run the generator again.
