The documentation is minimal, but see also http://gcc.gnu.org/onlinedocs/gccint/Types.html A typedef statement will normally create a TYPE_DECL node. For a TYPE_DECL x, DECL_NAME(x) is the name of the typedef, and TREE_TYPE(x) is the type. DECL_ORIGINAL_TYPE exists mainly for debugging information. Ian
