Exactly this, and the case is also vice versa with gdc. The druntime reference
library also does many things that are unreasonable and incompatible with gdc (and
I assume ditto ldc too).

One future plan on my list is the restructuring of core/stdc to be more ports
friendly (the source, not the installed files) - something to help push along ARM
development for D2 with GDC, and hopefully for other archs to follow pursuit. The
result being one elongated patch that won't be accepted upstream for sure. :~)
