The issue here is one of binary compatibility. gcc 3.2 and gcc 3.3 were not
that much different, and gcc 3.4 and gcc 4.0 are not that much different.
Where large differences occurred was between 3.3 and 3.4. We can't ship compat
versions of every compiler, so we have to pick and choose.
I'd note that for OpenOffice.org, which happens to be 7 million lines of C++,
there was a _huge_ patch for gcc 3.4 compatibility, but the patch for 4.0 has
mostly been naming anonymous enums (ie, instead of "enum {...};" it now has to
be "enum foobar {...};").
If we can do OpenOffice.org for gcc 4.0 in a week, others can certainly do their
C++ programs which aren't near that size. So the answer here is really "fix
your code", since you already did most of the work porting to gcc 3.4.
