Turned off -W and -Winline so that the warnings that should be fixed for

2.2 are more obvious.  -Winline is unimportant, but -W gives thousands
of warnings for comparisions.  Turning off -W also loses warnings for:
- auto variables clobbered by longjmp.  Not much of a problem in the kernel.
- functions returning without a value.  I don't like losing this.
- an expression statement or the left side of a comma operand contains no
  side effects.  Turning this off also stops warnings for the low quality
  debugging macros in gsc.c and lpt.c.

Should be in 2.2.
