How to make GnuWin32 portable.
- Install all the GnuWin32 packages you require on a "build" computer. The packages are normally installed in a "GnuWin32" folder.
- Copy the GnuWin32 folder from your "build" computer to your portable drive or target computer.
- On your target computer, add the path to the GnuWin32\bin folder to your user (not system) PATH environment variable.
(Moving to portable applications to save time installing programming tools each time I have to work on another computer, especially when I don't have administrator rights.)
