[LC++]Compiles with g++-3.2 but later versions flakey. Why?

[Dr Mark H Phillips]

Hi,

I've attached some test code below.  It compiles fine with
g++ version 3.2.3, but fails for later versions.  The strange
thing is that different versions fail in different cases.  Have
I uncovered genuine compiler bugs, or is there something else
going on?

Here's the errors I'm getting:
$ g++-3.3 testit.cc
testit.cc: In function `int main()':
testit.cc:22: error: `dummyx::dummyFunct' cannot be used as a function
$ g++-3.4 testit.cc
testit.cc: In function `int main()':
testit.cc:23: error: `dummyx::dummyFunct' cannot be used as a function
$ g++-4.0 testit.cc
testit.cc: In function ‘int main()’:
testit.cc:23: error: ‘dummyx::dummyFunct’ cannot be used as a function
$

Thanks,

Mark.
