PageCache.cpp lines 269..273: -- cut here -- #if ENABLE(WML) && !frame->document()->containsWMLContent() && !frame->document()->isWMLDocument(); #endif && frame->loader()->client()->canCachePage(); -- cut here -- Obviously, if WML is enabled, the build fails.
Still present in trunk.
Confirmed this breaks the build when building with WML support.
Committed build fix in changeset 64019 <http://trac.webkit.org/changeset/64019>. Unfortunately, this fix alone does not fix the build when compiling with WML support enabled. See Bug #42943 for more details.
