darcs patch: Support an interrupt flag, and primitive... (and 4 more)

["Márton Sasvári (IJ/ETH)"]

I've tried the process described below to work around the InterruptFlag 
issue, but 'make newboot' got into an infinite loop after stepping into 
the debugger. The original problem is that it does not find the message 
#parenthesizes on 'repl resource'. All this on cygwin.

What is the current workaround the InterruptFlag or I should not bother 
as I've just restarted work on the json parser ?

Regards,
Marton
