Ahh, this is because I passed them as a single argument.  I switched
it to multiple arguments which should fix it.

ie this:

>> > myPpC2hs inFile outFile verbose
>> >     = rawSystemPath verbose "c2hs" ["-o" ++ outFile, "ip_icmp.h", inFile]

Is now this:

>> > myPpC2hs inFile outFile verbose
>> >     = rawSystemPath verbose "c2hs" ["-o", outFile, "ip_icmp.h", inFile]

Can you try that out in your hook and see if it works?
