[Bug c/22240] New: ICE with transparent unions, function pointers and -pedantic

["jsm28 at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

typedef union { union w *u; int *i; } H __attribute__ ((transparent_union));
void (*h) (H);
void g (int *s) { h (s); }

yields an ICE when compiled with -pedantic.  Not a regression.  See discussion
at <http://gcc.gnu.org/ml/gcc/2005-06/msg00914.html> and thread;
DECL_IN_SYSTEM_HEADER is being checked on a NULL fundecl.
