I just tried to compile the GNU CC version 4.2 snapshot 20060211 with
the Intel C compiler.
It said
../../src/gcc-4.2-20060211/gcc/c-decl.c(4523): remark #593: variable
"type_as_written" was set but never used

was set but never used

I've checked all of these, and they all look like local variable that can
safely
be deleted to me.
