Yes.

Okay, then I'll use that.

I've built and installed the posix library, with "make realclean; make build; 
sudo make install" now. And: it works. It installs the "posix" bits in "/usr/
local/mercury-rotd-2019-03-21/lib/mercury" now. There they are found when 
doing "mmc --make hello1 --ml posix". No more "--mld" needed.  :-)
