RFC: Removing --enable-win32-registry?

[Richard Kenner]

    Or does it affect every time that GCC is executed, i.e. does GCC look
    for the registry key to find the location of the components to execute?

The latter.

    Also, since you mentioned that it installs other keys, do you happen
    to know what other keys?

"it" is not well defined.  I don't *know* what the current installers do
and I don't *remember* what the original one that I wrote did.
