Code:Blocks forum,
Here's the information I left out in my original post.
I am running Code::Blocks version 16.01 on Windows 7 Professional SP1
The compiler I use is Mingw32 and search directories set to
C:\SDL2-2.0.5\include\SDL. There are no relative paths in my setup.
When I build a simple "Hello World" program there are no errors and
it runs successfully. If I add #include <SDH.h> and try to build it
again I get the error message 'undefined reference to 'WinMain@16'
File name is main.cpp
#include <SDL.h>
#include <iostream>
using namespace std;
int main()
{
cout << "Hello world!" << endl;
return 0;
}
BUILD LOG WITHOUT #include <SDL.h>

OTHER THINGS I HAVE TRIED
There was a suggestions on the web regarding placing -mwindows as compiler
flag which you can see in the Build logs.
Select the checkbox in Settings-> Compiler > Build options "Explicitly add currently compiling file's directory to compiler search dirs".
Closing and reopening Code:Blocks.
Go to project > build option and put a check mark on "Have g++ follow the C++11 ISO C++ language standard [-std=c++11]".
project --> build option Put check mark on " Have g++ follow the C++11 ISO C++ language standard [-std=c++11]"
Any suggestions?
