I'm not passing an argv array, but a single string. I admit that I could
have renamed arglist into something else...
And yes, this string is leaked. There should be a call to clear_args()
before the final exit().

Also the pclose() should be called three time when rpcgen is invoked with
no flags (parses 3 times the input), but the fclose was already
missing in the current version and I wasn't 100% sure why.

Yes that's true, I missed this one. Ideally the input file should be
passed through cpp's stdin. But I'm not sure if '-' as a filename can be
used in a standard way?
