My understanding is that the traditional GCC and C99 interpretations for 
"inline" and "extern inline" are basically reversed.  So "inline" is just as 
much a problem as "extern inline" -- although we seem to have been getting away 
with "inline" for a while in intervals.c and elsewhere (unless we're defining 
it away on more platforms than I would hope necessary).  Even so, I generally 
consider "static inline" to be the only safe form, unless you want to jump 
through hoops to figure out or force the interpretation of "inline" or "extern 
inline" with your particular compiler.
