anonymous struct problems

[Ben Guthro <bguthro at sequelimaging dot com>]

I'm running into a problem that I did not have in previous versions of
gcc
(I'm running 3.3.2-1 - shipped with Redhat Fedora Core1)


previous versions of gcc only gave me warnings on this code:

typedef struct DigitalMonitorPhotometry
{
	union
	{
		struct
		{
			DMC Brightness;
			DMC Contrast;
			DMC RedGain;
			DMC GreenGain;
			DMC BlueGain;
			DMC RedBias;
			DMC GreenBias;
			DMC BlueBias;
		};
		struct
		{
			DMC dmp[8];
		};
	};
}DM_PHOTOMETRYSETUP;


However, now I get:
error: ISO C++ prohibits anonymous structs

This used to be a worning under previous gcc versions.

Now, this works under M$, Codewarrior (with a pragma) and other
versions of gcc...do I need to be adding a new flag here, or is this
something that just is no longer supported.
