That patch also fixes the FAIL of testsuite\g++.old-deja\g++.dg\other>g++
pr35504.C .  Currently it fails on mingw32 and cygwin with:

[Bug target/38054] Assertion failed in change_decl_assembler_name()

[hackbunny at reactos dot com]

------- Comment #8 from hackbunny at reactos dot com  2008-11-24 10:29 -------
I have added a test case that shows a closely related issue with nested
functions, -funit-at-a-time and unreferenced file-scope externs (yes, if you
remove "int x = 0;" the warning goes away)

The "%D renamed after being referenced in assembly" warning cannot be disabled,
either, so this is a bit problematic for sources compiled with -Werror
