Array initializers should work in GCC-2.95.X also, your syntax is just a
little off ...

$ cat foo.c
struct foo {
	int bar;
	int baz;
};
                                                                                
struct foo fufu[] = {
	[0] = {
		.bar = 0,
		.baz = 0
	},
};

$ gcc-2.95 -c foo.c
$
$ gcc-2.95 -v
Reading specs from /usr/lib/gcc-lib/i386-linux/2.95.4/specs
gcc version 2.95.4 20011002 (Debian prerelease)
$

The above foo.c compiles fine with gcc-3.2 and gcc-3.3 also. The C99
syntax should be no problem for gcc-2.95, or really any GCC release
after gcc-2.5, as gcc-2.5 is where the current documents say the syntax
with the ":" became obsolete.
