I tried this, and decl_function_context works now without triggering  
an internal error. However, gcc doesn't accept the attribute:

  { "ms_hook_prologue", 0, 0, true, false, false,  
ix86_handle_abi_attribute },

My test file
int __attribute__((__ms_hook_prologue__)) testfunc()
{	
	return 0;
}

test.c:2:1: warning: ‘__ms_hook_prologue__’ attribute only applies to  
functions

Huh? As far as I understand C I am applying the attribute to a  
function in that code. I feel kinda stupid here. What's wrong this time?

I found the declaration of struct attribute_spec, but the comments  
didn't really explain to me why the function isn't a function.
