Yes/No? -- BBv2 always has this set to yes.
N=0 (off) -- <warnings>off N=1 -- Not supported N=2 -- Not supported N=3 -- <warnings>on N=4 -- <warnings>all
NOTE: <warnings> defaults to all by default, whereas the IDE defaults to N=3 (<warnings>on) by default.
VC6 does not have this setting, so it won't pick up the flag.
