find_template in parallel/find.h used to use a VLA, but Benjamin changed this
to use __builtin_alloca a couple of days ago because VLAs are not in C++98
and therefore trigger a warning.
He says the right thing to do is to use a VLA but make sure that the file
is recognized as a system header so that the warning is suppressed. This PR
is meant to remind him of changing things back to the VLA once he figures
out how to flag a header as a system header :-)
