Apologies for randomly parachuting into this email thread, but if
Meson doesn't support per-file compile flags then what's the plan
for handling the cases where we currently need per-file compile flags ?
(This is one of the things that I thought was quite a nice move
forward in our make infrastructure -- we now have clean syntax
for saying "these files need to be built with these warnings disabled
or these extra include paths or whatever" and also "these files
imply we're going to need to link against library X".)
