No, I gave up.
It is probably relatively more tractable in the new paser, but even
there it is probably not easy. I'm not sure what the new attribute
syntax document says about this case.

This is actually a regression from 3.0.4 so some patch made this fail.
>From Phil's regression hunter: Search converges between 2002-04-28-trunk (#75) and
2002-05-05-trunk (#76).
The only reason I say this was because Apple's 3.1 based compiler is based on 3.1
(20020420) which does not have this regression in it.

The regression in PR 7385 was introduced or exposed by this patch:
--- gcc/gcc/cp/ChangeLog ---
2002-04-30 Jason Merrill <jason@redhat.com>
* decl.c (grokdeclarator): Don't override TYPE_NAME of an
anonymous class with a typedef if there are attributes.
The regression hunt took place on i686-pc-linux-gnu using the submitter's
test case. Like many other recent hunts, it started with the dates
identified by Andrew Pinski using Phil's regression hunter.

This observed behavior was the intent of the patch. The gcc trunk gives this
additional error for your testcase:
error: `typedef enum <anonymous> e1' does not refer to the unqualified
type, so it is not used for linkage
You want to write
enum e1 { v11=1, v12=2 } __attribute__ ((packed));
instead, so that the attribute applies to the enum rather than the typedef. If
you want to use "e1" without "enum" in C, you can then write
typedef enum e1 e1;
