John David Anglin is the hppa/parisc gcc maintainer and has
commented on inline variants last year:
http://lists.parisc-linux.org/pipermail/parisc-linux/2005-October/027587.html
This makes me think -Wmissing-prototypes is reporting the wrong warning.
ie there is a prototype but no function and no label.
Can you check with gcc folks to see if this is a gcc bug?
The parisc point intentionally switched to "extern inline" at one
point and unless what jda wrote is now incorrect, I'm not inclined
to change it.

Yes, all the functions marked "extern inline" are expected to get
essentially the same treatment as "always_inline".
