Me too. I see this as mainly a problem with the compiler I use (GCC
4.1.2 currently) as it would be sensible for it to have a mode for
ignoring calls to deprecated functions from within a deprecated
function. It is inconsistent: it does ignore the use of deprecated data
types within a deprecated data type definition.

I don't know a way to do that.

+0. It sounds to me like that would be a relatively tidy solution. I
don't much mind that it involves moving some functions to a new source
file and separating Foo() and Foo1() from Foo2(). (For me, "jump to
definition" is the most important feature of any programmers' editor.)

OTOH, I have currently disabled put "CFLAGS += -Wno-deprecated" in
my ./configure options, and treat this as one of those warnings that
some of us will want to have a look at sometimes, but not most of the
time.

OTOH[1], it has clearly shown up a bunch of places where we weren't
aware that we were using deprecated functions, and people of gone and
fixed some/all of them, so the warning is clearly doing some good.

So, I don't really mind whether it stays as-is, or gets disabled by
default, or if we move the functions like you suggest.
