On modern CPUs it is much better to have one copy of the function
instead of inlining it. Making the functions static instead of extern
will probably cause wine to be a bit slower at the expense of silencing
some not very useful warnings. If you want to fix it for this case, I
suggest you add a define that changes to "static inline" if
pedantic/ansi mode is being used and "extern inline" otherwise and use
it when declaring the functions.
Well if it isn't applied (btw how could I see what is/isn't applied?) will try to look at that.
Though the keyword "inline" implies the code should get inlined, and if it shouldn't, the implementation copy should be removed from the unicode.h file
