I have no actual intention of doing so, although it increases the
complexity of the target headers.

Patches have been floating around, and I'm sure I could get them into
shape. My problem (apart from the same complexity problem as on SPARC)
isn't primarily cpu power of my testfarm, but rather the time it takes
to analyze and fix problems. This is practically doubled if you have
two different configurations to test, and I simply cannot afford that,
given that this is a spare-time activity. That's why I'm even opposed
to take patches, since than I'm forced to deal with issues as well.
Since the Sun Studio compilers are still exclusively 32-bit as wall, I
see no strong reason for GCC to be different.
