In a similar way entering denormal numbers, for example, could be allowed only when flag D is set. I'm not suggesting that it necessarily be so, just offering it as an option.

I made an effort to structure the code in such a way that if any of the settings are the same for flag D cleared and set, then only one code branch will be compiled in for the appropriate function instead of two. There's no need to remove anything from the code, unused portions are automatically eliminated.

I'd missed that completely. Thanks for the explanation. So there is no need for any further action unless someone is unhappy with the defaults you have chosen.

Many are probably unhappy with the current defaults because (1) they mimic the old behavior with simple limits and don't take advantage of the newly introduced intelligence in the code and (2) they also reproduce the odd and inconsistent behavior that allows [EEX] [3] [8] [4] [+/-] but not [EEX] [+/-] [3] [8] [4]. I set these defaults so they don't have to be changed yet again once a decision has been made. (The attached demo binary uses completely different settings than what's in mainline.)

I expect that once Walter, Pauli and Marcus figured out what should happen during exponent entry, we'll change the defaults. In the meantime I'm happy to discuss further ideas if anyone wants to suggest something I haven't already implemented as an option.
