This is one way, but as you noticed you need to be careful about gcc versions. There
are 4 porting steps involved: 2.10 (should just work given the right gcc version),
3.02, 4.08, and finally 5.02. Each step will require a particular gcc and perhaps
changes to the mangler.
This is a long and tortuous route to getting GHC working. There is a better way, as
suggested by Keith, namely to bootstrap from .hc files. The best version to start
from is 4.08(.2) (later versions have problems with .hc bootstrapping).
One can bootstrap the compiler using "unregisterised" .hc files, which avoids the
mangler. The process has been discussed on one of the lists before, but I just did a
search and couldn't find it - maybe you'll have better luck. Anyhow there are three
stages: first you generate the unregisterised .hc files using a two-stage bootstrap on
a machine with a working 4.08 GHC (eg. a Linux box). Then you compile these on the
target machine to generate a working unregisterised compiler.
Finally you can use this compiler to experiment with getting registerised builds
working - i.e. modifying the mangler.
Cheers,
Simon
