I agree, it should be a constant. I was cautious about adding it since it may also need to be part of the API for wrapping samtools - so best left to Heng Li to decide on.

As to your suggestion of setting fp->compress_level = 0, yes, assuming we need to worry about other compression levels that does make more sense. I asked about this on the mailing list.
