--- Comment #1 from Marek Polacek <mpolacek at gcc dot gnu.org> ---
Confirmed, mine.  Even GCC 4.4 ICEs.  And 3.4:

$ gcc34 -c z.c
z.c:1: error: `a' undeclared here (not in a function)
z.c: In function `fn1':
z.c:1: error: parameter name omitted
z.c: At top level:
z.c:2: error: redefinition of 'fn1'
z.c:1: error: previous definition of 'fn1' was here
z.c:2: confused by earlier errors, bailing out
