-fno is part of the default flags for all the v3 sources.  For the particular
case of concept-inst.cc, we override with the, uh, "-fyes" :-) form.

The options-parsing code will handle the switches in order, i.e., it will
first disable them, then later, will turn them back on.

... hm.  You might try compiling that file by hand, by copying and pasting
the long compiler command, but removing the -fno-implicit-templates bit.
If there's any difference at all in the generated symbol list, something
is very wrong.
