and cairo-qt.h added for --enable-system-cairo.

My build still fails but for unrelated reason:

for now you can try 
https://github.com/tmeshkova/gecko-dev/tree/embedlite_upgrade
which has more less compilable branch so no messages like src/base/moc_message_pump_qt.cc'...
Attached patch unhid, v1.1 (obsolete) — — Splinter Review

And it still doesn't help Clang while GCC builds fine.

I'd rather leave this alone until we figure bug 961264 comment 2 (feel free to participate).
Comment on attachment 8364133 [details] [diff] [review]
unhide cairo-qt.h

Clearing review request until we know what we do with the visibility flags.
Attachment #8364133 - Flags: review?(mh+mozilla)
comment 0 issue doesn't look trivial to me so it may be worth to think with bug 961264 in mind.

unhide cairo-qt.h

Comment 6 issue is an old one with trivial fix. It used to be enough to build against QT4 some releases ago.

Nevermind, it seems my clang i386 builder doesn't use gcc_hidden.h due to

checking For gcc visibility bug with class-level attributes (GCC bug 26905)... yes
