Subject: Add WX_ATTRIBUTE_UNUSED and use it for typedefs to avoid g++ 4.8 warnings.
X-Git-Url: https://git.saurik.com/wxWidgets.git/commitdiff_plain/540dacb643455dd391e43407ee0b3193467b9ee1?ds=inline

Add WX_ATTRIBUTE_UNUSED and use it for typedefs to avoid g++ 4.8 warnings.

g++ 4.8 warns about unused typedef's in local scope resulting in hundreds of
warnings when building wx, suppress them by using WX_ATTRIBUTE_UNUSED for
these typedefs.

Closes #15137.
