NULL function annotations

[Moritz Lenz]

Hi all,

I'd like to turn your attention towards
http://trac.parrot.org/parrot/ticket/2104

Quick summary: commit c1f77f7eb90041468c3b13f5b48ae2ca1d1c37a5 caused 
several spectest failures in rakudo. Rakudo is using NULL instead of 
STRINGNULL in src/binder/bind.c for initializing static variables. Using 
STRINGNULL instead doesn't work easily, because it's not a constant, so 
not allowed for initializing static variables.

Until sombody suggests a good solution I've created a branch called 
'pmcnull_annotations' which still contains the commit in question, and 
reverted it in master.

Cheers,
Moritz
