Minimum GCC version

[Robin Haberkorn]

Dear fellow Scintilla developers,

what's the current minimum supported GCC and Clang version?
After upgrading to v5.5.7 (or rather HEAD), I noticed that charconv is
used, which appears to require at least GCC 8.1 [1], although I can't
really confirm that.

At v5.5.4 I was assuming that the minimum version is GCC 5.0. But the
oldest I was building with was probably GCC 7.x. That was on NetBSD 10,
for which you will soon receive another patch. Actually I upgraded
Scintilla, so I can provide you with a patch that cleanly applies to HEAD.
It would be tragic if that broke my NetBSD port again. Although I could
just require a newer GCC from pkgsrc, I suppose.
I had v5.5.4 building on Ubuntu 14.04 via PPA even. Can't find which gcc
this had.
The upgrade also broke openSUSE 15.5-15.6. But again, perhaps I can pull
in a newer non-default GCC as a build dependency.

Best regards,
Robin

Ah, I see that in the release mail for 5.5.7, Neil actually states GCC
9 or Clang 9.
