Sorry, indeed the line 'n=1' is missing. Not sure how that single line got
lost.
There are a few possibilities as a work around for this simple case, but the
context where I came upon this bug is (as often)
The and headers need their counter parts and
from the libc respectively, but libstdc++ wraps these
headers. Now and include these headers using
$ echo '#include ' | g++ -x c++ -E - -isystem /usr/include >/dev/null

Fixes std.array.Appender and RefAppender to use .opSlice() instead of data()
Previously, Appender.data() was used to extract a slice of the Appender's array.
Now use the [] slice operator instead. The same goes for RefAppender.

We issue bogus -Wparentheses warnings (3 of them!) for this fold expression:

Firstly, issuing a warning for a compiler-generated expression is wrong
