I don't know what I was thinking when I wrote this, but the following illegal
code (.ii, tiny testcase) causes an ICE in g++-4.0 which was not present in 3.4:

# 1 "extern-static.cpp"
# 1 "<built-in>"
# 1 "<command line>"
# 1 "extern-static.cpp"
struct foo {
  extern static int i;
};
int main () {
  return 0;
}

The output I get is:

dr@peaceful:~/src$ g++-4.0 -save-temps -o extern-static extern-static.cpp
extern-static.cpp:2: error: multiple storage classes in declaration of ‘i’
extern-static.cpp:2: internal compiler error: tree check: expected var_decl or
function_decl or parm_decl, have field_decl in grokdeclarator, at cp/decl.c:8161

The several versions of gcc I have, I got as debian packages. The output of gcc
-v for my 4.0 and 3.4 builds, respectively, are:
