I don't want to be a hair-splitter, but I do think this message does
belong in gcc - it's a question of functionality, and how easy to use
gcc is.

I am trying to move to gcc-4 for its technical improvements, but I'm
finding that it seems to be far less forgiving than gcc-3.

This is having the unfortunate side effect that a lot of packages that
used to compile perfectly fine with gcc-3 are no longer doing so with

IMO it should be flexible enough to 'do the right thing' when it can.
>From the point of the user, it makes it far more user friendly than
otherwise. Is there a flag, environmental variable, or some switch
that I can use to make gcc-4 have the older, looser behaviour? (ie: to
be backwards compatible with the large volume of code I compile and

Here's another example I'm finding:

Constructs of the form

extern enum vtype iftovt_tab[];

are now failing with forgiving

error: array type has incomplete element type

This would be fine if it was code that I controlled - but the matter
of fact is that this code is in /usr/include/sys/mode.h, which comes
bundled with solaris 10, and the upshot is that I'm going to have to
somehow hack solaris headers in order to make gcc-4.3.2 be able to
compile perl-5.10.0.

Which is just plain wrong.
