Well, it turns out that at least some compilers (AIX's) are really

be a problem with things like HAS_STDLIB_H, which is common enough to
cause collisions. So, we need to go name-prefix all the #defines.
So, the project.
The current implementation of find_lex (by_name) is suboptimal. A linear
scan over the list of lexical names is performed
(s. sub.c:lexicals_get_position()).
A better way would be to provide a list of lexicals plus a name hash,
where hash values are indices into the list.
What would be a

Remember, the pad depth reflects lexical scope nesting,

A test for seek and tell is added to t/pmc/io.t

Windows is untested but I hope i got the things right.

Always.

This prints:

There are a number of ops that could fail. Examples are find_lex but
also the various load and lookup ops. Options for handling failure are:
- Abort parrot
- Throw an exception
- Return a default (null) value
I think it is hard for the parrot designers to decide what language
implementors want

With the workaround it runs fine now.
