Right, that's much better!

These names look OK to me.

… unless "defaultcomp" remains unofficially supported for a little
while, with a mere warning displayed, so that everyone learns about
the transition they have to go through. I prefer such approaches to
the flag day one that assumes everyone is on top of their tails-dev@
backlog etc. :)

Yeah, and it even used to be even worse, cause we hadn't unambiguously defined 
when a "release build" should occur before, but since the recent rework of the 
build system this is well-defined (build a release if and only if HEAD is 
tagged). Any way, a ticket and patches renaming them to `fastcomp` and 
`releasecomp` (or similar) would be welcome. This change will require some 
coordination with our infra's sysadmins, though, so it might take a while for 
it to be applied.

Cheers!
