Using GCC v4.0_20041107 on FreeBSD v5.3:

struct __attribute__ ((visibility("default"))) Foo { int foo; };
int main(void) { Foo foo; return 0; }

If compiled as a C++ file, all is fine. If compiled as C you get:

internal compiler error: tree check: expected class 'declaration', have 
'exceptional' (identifier_node) in handle_visibility_attribute, at c-common.c:
4648
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.

I think it's perfectly valid for C code to mark structures as having visibility 
though it means nothing useful (so it could simply be ignored). It certainly 
shouldn't generate an internal compiler error.

Cheers,
Niall
