Is NetBSD similar to FreeBSD in that you have 80-bit reals but
only the first 53 bits of the mantissa are used?
I don't know how accurate LDC is when it sets up compile time
float properties. But what do you get when:
pragma (msg, real.sizeof);
pragma (msg, real.mant_dig);
Alternatively, use a C program with printfs for:
sizeof(long double)
LDBL_MANT_DIG
To make sure both ldc and gcc are agreeable.
Have a look at rt/dmain2.d (look for fldcw) if the problem is
because of
what I describe above.
I suppose it is not similar FreeBSD ( according
