Sorry, did not understand that phrase, and google translation
was not much helpful. But I feel you were not saying how much
you loves me :-)
The patch as a whole may not be required to apply, and not
that patch "verbatim", as it would require still at least a
review to ensure every sdk header "passes" the:
when it is applicable. But always including it would not really
be a problem, just that those bits are only required before
installing the headers, i.e. in the X Server build.
To apply a minimal amount of the patch, it would be required
to just add the proper
#endif /* FOO_H */
to the headers that don't guard agains't multiple inclusion.
And a more complete work is to only define in "sdk headers"
those symbols that should not be available to drivers.
Anyway, the current code is ok, and should require minimal
maintenance work to compile the X Server and modules with
hidden symbols by default (most of it is just changing a header
instead of hunting symbols in the C sources, that have theirs
names frequently generated after macro expansions...).
