[Bug c++/31078] [4.3 Regression] warning: same canonical type node for different types with const strings

I definitely think this should be an error, not a warning.  I only saw this
problem by luck.  I'm compiling the entire Debian archive (ie 7000 packages)
on IA64 with GCC 4.3 and I cannot look at every log file (especially when
the build was successful).  I only noticed this one because the program
failed to compile later on and I looked at the log to see the error.

Anyway, are there any other warning messages like this one?  If so, I can
search
my log files.

This warning is really frequent.  I can find 2200 warnings that mention const
and same canonical type node for different types.  Some don't mention
const;
I'll look at them and file separate bugs.

Yes, the one reported in PR middle-end/30666.

Another problem is that this warning does not always occur, even when I use
the same source and options.

| I think the warning message should be more explicit. It should say: this is a
| compiler bug, please report it, or something similar.

I thought we eventually agreed that it should be a plain internal_error.

Warning is for constructs in user codes, nont compiler internals.

Nevertheless, I think we should mention that this is a bug, please report it,
so early testers would know what is going on.
