This was sort of the idea, but I see some disappeared.

Probably best for now.  Eventually, I'd like it to look more like the
AC_PROG_CXX code, all in one place.  Right now the templates are a
safe-guard against trying to build on a platforms that's not supported at
all, but it should actually be possible to do just that, without shared
libraries maybe, and with the software-TAS that you implemented.  But ISTM
that we've covered the recent wave of new operating systems, so this is
not a pressing issue to me.
