How do I add the MinGW bin directory to my system path?

To change the path on Windows XP, follow these instructions, and then add the directory where you install MinGW plus bin. Example: if you install MinGW in C:\ then you have to add C:\mingw\bin to your path

Just for completeness here are the steps shown on the link:

1. From the desktop, right-click My Computer and click Properties.
2. In the System Properties window, click on the Advanced tab.
3. In the Advanced section, click the Environment Variables button.

4. Finally, in the Environment Variables window, highlight the Path variable in the Systems Variable section and click the Edit button. Add or modify the path lines with the paths you wish the computer to access. Each different directory is separated with a semicolon as shown below.

   C:\Program Files;C:\Winnt;C:\Winnt\System32;c:\mingw\bin
