Thank you for doing this. This sort of feedback from large and diverse
user communities is very helpful.

That sounds like a good plan. I haven't tested it for years, but a long
time ago I did find a measurable difference between -fpic and -fPIC.
However, the safer default of -fPIC makes sense. If anyone would care to
test -fpic for a particular architecture and override the default for that
particular architecture, that would be fine too, but as you say, the safer
choice should be the default.
