In preparation for the future transition to subversion, I've written
some code to merge the old-gcc repository into current mainline. I
would like to see this merged repository used as the basis for the
conversion to subversion. The advantage is that it provides revision
history back to 1992, whe

Thank you for your quick reply. I have a few more comments though, and
I hope you can take a look at these.

I beg to disagree: first, we again raised the GFDL issue with RMS,

Can someone please point me to a place where I can get information
about how gcc (2.96 and later) lays out class instances? In other

to the pointer correspond to the

Why not check out my recently posted -Wpragmas patch on gcc-patches?
It takes a set of existing non-optional warnings, and gives them an
option that can be used to disable them, which defaults to on
(i.e. -Wno-pragmas is the useful option).

First I'll note that you shouldn't see this when using the DFA

when using the old pipeline description (define_function_unit, etc.).
