Just use g++ -v or gcc -v which will give you your compiler version.
You can also go to your windows settings, click on "Apps" go to the search bar and search up c++ scroll down to the last item, and click on it. The version should be displayed fairly obviously for you.

I downloaded and installed MinGW. Typing gcc in the Windows command line prints: gcc is not recognized as an internal or external command

Very simple.
Go to Command Prompt and type
gcc -v
if gcc is installed on your PC, it should display a host of information, starting with the sentence
Using built-in specs
and that will indicate that gcc is installed on your computer.
Windows 8 - right-click on the Start Button and select Command Prompt. For older Windows systems, click the Start Button and in the search box type “cmd""
In the Command Prompt window type “gcc” and hit enter. • If the output says something like “gcc: fatal error: no input files”, that is good, and you pass the test.
The symlink to the 4.8.2 directory is nothing to worry about, it's normal for the libstdc++ headers on Red Hat Enterprise Linux (and therefore CentOS) to be arranged like that.
gcc --version will tell you the version of the gcc executable in your path.
rpm -q libstdc++-devel will tell you the version of the package that owns the C++ standard library headers.
rpm -ql libstdc++-devel will list the files installed by that package, which will include the files under /usr/include/c++/4.8.2
rpm --verify libstdc++-devel will check that you haven't messed up the C++ headers by replacing them with something else.
The error is more concerning, that implies you have messed something up. My guess would be it's in the from [...omitted by myself as it is irrelevant] part, which may actually be very relevant. std::locale should be declared in <bits/locale_classes.h> which is included before <bits/locale_facets_nonio.h>, so if it wasn't declared my guess is that you have some header that defines _LOCALE_CLASSES_H and prevents the standard library header from being read. Do not define include guards that start with underscores, they are reserved names.
I am not quite sure but below is more information

Run gcc --version, the result will be something like this:

If this doesn't work you might not have the compiler setup in your PATH correctly (I believe this is common if using MinGW on Windows), in which case you can first check where the compiler is located by doing the following within Code::Blocks:
- Menubar
Settings->Compiler and Debugger - Select
GNU GCC Compiler - Select the
Toolchain executablestab
Then, using a command line, move to the directory given, then in to the bin subdirectory, then try running gcc --version from there.
Typically execute the command
gcc --version
and it should give you result like this:
gcc (Ubuntu/Linaro 4.4.4-14ubuntu5) 4.4.5
