There are two main environments A and B, and it manages to build on A, 
because the build process depends entirely on shell commands, utilities 
and libraries that are exclusive to A.

However the software I create for B doesn't rely on anything exclusive 
to B, so can be built on A or B. Which process is more portable?

BTW see: https://gs.statcounter.com/os-market-share/desktop/worldwide

This is market share of desktop and laptops OSes:

  Windows   70%
  OS X      16%
  Linux      4%
  Chrome     2%

For all devices including phones and tablets, Windows is at 25% market 
share.
