Re: x86-win32 registry lookup patch

    Encourage the use of which -- the registry key or GCC_ROOT? 

Either, because they are completely equivalent.

    Sorry, but the registry key is a bad idea as it messes with other
    installations in a hidden way. Unless it's written to be distribution
    and version specific, by modifying the key, it should be at the very
    least optionally compiled in.

I don't follow.  Can you give more details?

    [1] For x86-win32 distributions, I add some patches that make these
    packages completely relocatable without any environment variable. I
    believe this code should eventually make its way into the GCC
    distributions, even if its use is optional controlled via configure.

But why not do this with the registry key?  That's how other packages do
it on win32 and what the mechanism was designed for.
