Tutorial: Installing portable MinGW C-Compiler gcc on USB Flash Drive / Stick

If you work on different computers, but always want to have a C compiler with you, just create a portable version on an USB flash drive:

1. Install MinGW to your computer, e.g. "C:\MinGW\"
2. Copy "C:\MinGW\" to the USB drive "X:\MinGW\"
3. Create a text file "X:\MinGW\bin\setpath.bat" with content set path=%path%;%CD%
4. Run the batch file "X:\MinGW\bin\setpath.bat"

Now the bin directory of MinGW is in the search path. Now you can use the compiler gcc or other MinGW tools...
