Subject: Disable symbols visibility support for the Clang compiler.
X-Git-Url: https://git.saurik.com/wxWidgets.git/commitdiff_plain/7198c3368055d88249a338eb33b21f051f674806?ds=inline

Disable symbols visibility support for the Clang compiler.

Even Clang++ shipped with Xcode 4.1 still can't handle visibility
of non-inline methods in exported template classes if the default
visibility is 'hidden'.

Disable visibility support for Clang for now, we'll revisit it in the future.
