As far as I can see, struct A does not have a copy assignment operator
at all.

The patch at http://gcc.gnu.org/ml/gcc-patches/2009-04/msg02133.html does
indeed fix the build failures at r146820.
Now regtesting and also at r146851. There's a build error in libgcc2 In
function '__udivdi3' for that

Is this any better in man4?
Todo should be killed.
Should all man pages based on libstdc++ include files and not class objects get
the axe?

2) Someone please add a stub to libstdc++ for __signb...@glibcxx_3.4 that
calls
__signbitl in glibc.
Hmm. Well, you cannot actually add a new symbol versioned for the first release
in the ninth release. That is

unfortunately, just assuming gc-sections work because `ld -v` shows gc-sections
won't fly: in the past this would have given false positives on some platforms.
This is different than the relro case.
Something to try

expand_phi_nodes can and will create RTL code so we need to register the RTL
CFG hooks before calling it.
Nope, that won't fly (for the moment). expand_phi_nodes also split edges
and it's necessary that this is

If somebody can explain why it's
necessary to let the generated RTL code depend on the IR mode, we could
possibly find a good way around this limitation.
Because we don't want to mark
