If you're going to use a statement-expression, you need to check that you're being compiled with GCC; tree.h uses

#if defined ENABLE_TREE_CHECKING && (GCC_VERSION >= 2007)

-         if (highest >0xF0000000)
+         if (highest > 0xF0000000)

Unnecessary whitespace change.

OK with those changes.
