tango.math.IEEE triggers static assert on SPARC

Description

I've been trying to build Tango on SPARC, but since IEEE fails, quite a few other modules fail too.

The static assert on line 121 is triggered.

Apparently the machine is a 64 bit sparc, but the OS (Debian Linux) is running 32 bit user space

How big is a real on SPARC? Presumably it's neither 64 nor 80 bits. What is real.mant_dig?

Printing real.mant_dig with Stdout yielded 113 - hopefully it is correct, at least the formatter looked like it worked with ints (it hung on double/reals).

Quadruple precision reals! Cool! I'll have to create quadruple precision versions of all the IEEE code. This make take a little while, but it's great -- it will ensure that the design is completely sound.

oh man :)

(In [3173]) SPARC is BigEndian?, refs #884

Compiling IEEE now gives

tango/math/IEEE.d:218: Error: undefined identifier UNDERFLOW_MASK

After [3177], I still get these (version id SPARC)

tango/math/IEEE.d:264: Error: undefined identifier INEXACT_MASK
tango/math/IEEE.d:266: Error: undefined identifier UNDERFLOW_MASK
tango/math/IEEE.d:268: Error: undefined identifier OVERFLOW_MASK
tango/math/IEEE.d:270: Error: undefined identifier DIVBYZERO_MASK

tango/math/IEEE.d:472: Error: can only * a pointer, not a 'int'
tango/math/IEEE.d:1079: Error: undefined identifier e

Note that since this is GDC, stuff probably will fail to some degree anyways even when it compiles.

status changed from new to closed.
resolution set to fixed.

After [3180] and [3181] it compiles on SPARC - great! Closing this - will open new tickets if there are sparc specific unittest problems.
