The khash functions are very small, so it very well may make sense for
them to be inline.

git-compat-util.h (or compat/msvc.h) defines __attribute__(x) to an
empty sequence of tokens except on HP C and gcc.  Attribute unused has
existed at least since GCC 2.95.

Unfortunately HP C doesn't support attribute __unused__. :(

On the bright side, it would be easy to work around using a
conditional definition of MAYBE_UNUSED for the sake of HP C.  From
August 2010 until March 2011 nobody noticed.
