[IPython-dev] Problem when sys.argv does not exist

[Adam Hupp]

I'm running into a problem embedding when sys.argv is not defined.
I'm running ipython from a C extension that does not set sys.argv.
The root of the problem is that DPyGetOpt unconditionally checks the
passed arguments against sys.argv.  With no sys.argv this raises an
exception and aborts the whole program.  Checked against 0.5.0.  The
following change to DPyGetOpt.py should fix it:

<               if args == sys.argv:
<                       args = sys.argv[1:]
---
>               if hasattr(sys, "argv"):
>                       if args == sys.argv:
>                               args = sys.argv[1:]
