Well Robert Dockins gave you an excellent explanation. You're just unlucky at the moment with 6.4. 6.2.2 is excellent - for various reasons I've had to stick with it for completion of some of my research.
Having the compiler able to compile itself, yes. Making that the only way to compile it, that's another thing.
The .hc files exist for this reason. However for a popular platforms this isn't usually a problem, someone does the port quite quickly. You're just particularly unlucky with 6.4 since there has been substantial reworking of the internals.
