Subject: How to mask out denormal operand exception?

Hi.

After using djgpp for some time (it works like a breeze, thanks dj),
I've finally run into an annoying problem: occasionally execution is
terminated by a "denormal operand exception" (I use an IIT 387).

After a short peek at the 387 programmers ref. I find that it should
be possible to mask out this exception, at the risk of loosing
accuracy.  Since I don't really need the accuracy (my neural network
might even benefit from a little added noise :-) , I would like to
hear if there is a quick'n dirty way to mask out npx exceptions?
preferably without recompiling the extender (I don't have access to a
386 BCC/TASM).

Thanks in advance.
