[PD-dev] type-punned pointers again

[Hans-Christoph Steiner]

Hey all,

Its time for the biannual post about type-punned pointers.  The good  
news is that in 0.41.4, it seems that Pd itself no longer as any type- 
punned pointers that gcc auto-vectorizer complains about!  The bad  
news is that there are still a handful of externals that do.  I'd  
happily fix them if I know how, but C pointer tricks are my weak point.

Here is a list of all the spots in question, generated by this script:
