[Bug pending/31709] New: combine and __attributes__((__packed__)) conflict.

[matt at 3am-software dot com]

a.c:

struct f { int i; } __attribute__((__packed__));

const char *foo(struct f *);

b.c:

struct f;

const char *foo(struct f *);

c.c (identical to a.c):

struct f { int i; } __attribute__((__packed__));

const char *foo(struct f *);


gcc -fsyntax-only -combine -ffreestanding a.c b.c c.c 
c.c:3: error: conflicting types for 'foo'
b.c:3: error: previous declaration of 'foo' was here

There is no difference even if b.c includes attribute((__packed__)).  Changing
the order such that b.c is either first or last suppresses the error.
