Ah, the C++ compiler.  You didn't say which it was.

Hmm, there seems to be something else wrong:

$ cat test.c
int foo() { baz; }
int bar() { baz; }
$ g++ test.c
test.c: In function `int foo()':
test.c:1: `baz' undeclared (first use this function)
test.c:1: (Each undeclared identifier is reported only once for each function 
   it appears in.)

$ gcc test.c
test.c: In function `foo':
test.c:1: `baz' undeclared (first use in this function)
test.c:1: (Each undeclared identifier is reported only once
test.c:1: for each function it appears in.)
test.c: In function `bar':
test.c:2: `baz' undeclared (first use in this function)

They really ought to give identical error messages.
