Working without GC

[solidstate1991 via Digitalmars-d]

Here's my ADPCM/etc. codec library: 
https://github.com/ZILtoid1991/libPCM

I have an intent to keep a mostly GC version (where the codecs 
are still noGC for minimal CPU overhead, so the best of both 
worlds), I'm planning an embedded version without the file 
operations, and one that has the file operations but don't depend 
on the GC. I had some attempt at this, but gave up due to the 
complexity of working with multiple pointers (and with pointers 
to pointers).

Some suggestions on it? Also feel free to either suggest new 
codecs (G726 will be my next target).
