Careful code uses __extension__. Here the excessive underscores must be used because the gnuish spelling for __extension__ is not aliased to a good spelling. 27 lines in RELENG_9 use some form of typeof, and 10 of them actually have the preferred spelling, with the unpreferred one mainly in newer non-core code: xfs: 6 lines with typeof, but 2 of these #define typeof as __typeof if typeof is not defined, which should be always reiserfs: 2 lines with __typeof__ drm: 4 lines with __typeof nxge: 1 line with __typeof net: 1 line with __typeof i386/include: 1 line with _typeof by me; 2 lines with __typeof__ (xen) xen: 5 lines with typeof amd64/include: 1 line with _typeof by me; 2 lines with __typeof__ (xen) sys: 2 lines with __typeof Bruce
