So, you have it, but you do not use it.

Huh, why?  Some reason other than testing or curiosity?

Oracle killed SPARC in 2017.  Rumours that Fujitsu may revive it.

POWER is still a thing.

I'm sure I had no point.  Just collectng data points.

"obviously" gpsd should support big-endian.  Actually making that
happen is not so easy.  C99 is clear that much of C99 is implementation
dependent.

gpsd has a lot of code solely for the purpose of supporting big endian.
Any of it could be affected by bit rot when untested.
