[Haskell-cafe] ghc wiki registration failure ( was: Failure in GHC compilation)

[Daniil Elovkov]

Hi
I wanted to add a couple of words that another solution would be to
add an option to xargs in target.mk
         xargs -n NNN
where NNN is less than the OS limit.

(That helped me to build LambdaVM on windows, there are quite a lot of
class files there, and no SPLITOBJS will obviously help)
Editing target.mk isn't a good thing, probably. Maybe some $XARGSOPTS
could be introduced...

BUT trying to register on the wiki resulted in an error with this
python traceback

Traceback (most recent call last):
