Hi,
my apologize for the breakage. I somehow missed Ada in --enable-languages
list. I've comitted the following fix that also cures enable checking failure
of g++.dg/torture/pr46154.C
Honza
* cgraphunit.c (varpool_finalize_decl): Allow external decls.

Not sufficient it seems:

I suppose so. I tested x86_64/linux with Ada.

It presumably breaks Ada bootstrap on x86/Linux:
/home/eric/build/gcc/native32/./prev-gcc/xgcc

-B/home/eric/install/gcc/i586-suse-linux/bin/
