The -Wno-parentheses switch will turn off those warnings...

Yeah, I noticed that too... it looks like with the standard gcc 2.8.1,
there's no way to turn off the warning about main(); in one place, it
issues the warning if warn_main is true, but in another place, it warns
when warn_main is _not_ true... very strange. The egcs in the NetBSD
tree has the latter warning #ifdefed out though.
BTW, perhaps you'll have better luck than me, but a mac68k kernel
cross-compiled from NetBSD/i386 with gcc 2.8.1 hung during the adb probe
(HWDIRECT ADB on a 660av). gcc 2.7.2.x and the NetBSD's egcs produce a
working kernel though.
