[PATCH] Fix PR debug/11816

[Ulrich Weigand]

Hello,

after running into the issue described in PR 11816 (dwarf-2 info 
for anonymous struct members is not generated), I've had a look;
it would appear this is easy to fix by the following patch.

Bootstrapped/regtested on s390-ibm-linux and s390x-ibm-linux;
no regressions in the gdb testsuite.

OK for mainline/3.4?

Bye,
Ulrich

ChangeLog:

	* dwarf2out.c (gen_decl_die): Handle anonymous struct members.
