Modern C++ means at least C++11 today.

C++11 is a quite complex language. AFAIK only two free software 
compilers support it: GCC and Clang/LLVM.

Both are coded in C++, but old versions of GCC have been coded in C.

If you only have a C99 compiler available, the usual way to get a C++11 
compiler is to

compile a GCC which have been coded in C (not C++). So start with GCC 4.4.

Then compile GCC 4.4 with your C compiler.

compile the next version of GCC with the previous one, so

    compile GCC 4.5 with GCC 4.4
    compile GCC 4.6 with GCC 4.5
    compile GCC 4.7 with GCC 4.6

if you are lucky, you might you might skip odd versions, e.g.

    compile GCC 4.6 with GCC 4.4
    compile GCC 4.8 with GCC 4.6
    compile GCC 5.2 with GCC 4.8

you could replace the last step with compiling Clang/LLVM (e.g. 3.7) 
with your last GCC


Cheers
