to be executed even when -n is given on the command line to make. This is
very handy for calls to submakes.
This is slightly changed from the original patch as obtained from NetBSD.
The NetBSD variant prints lines which have both '+' and '@' when -n
is specified. The commited version always obeys '@'.
Bump MAKE_VERSION so Makefiles can use this conditionally.

in the options themselves, but is sufficiently astonishing that I think it
deserves a BUGS entry as well.)
section.
Move the HISTORY section to place it before BUGS rather than after BUGS,
in order to minimize the chance of this error being reproduced in the
future. (Both mdoc(7) and 63% of manual pages have these sections listed
in this order.)
- 'savech' is only used if it is set a few lines above where
it is used, initialize it to silence warning.
- 'length' is either -1 or greater than 0, hence it is safe to cast it
to unsigned when comparing it here.
odsyntax.c:
- 'p' is assigned either (*argvp)[0] or (*argvp)[1] which both are
char *. 'num' and 'end' are assigned values based on 'p'.
Hence use char * instead of unsigned char * for these variables.
'&end' as the second argument to strtoll does not need to be casted
to char** any more.
This solves a
'dereferencing type-punned pointer will break strict-aliasing rules'
warning when compiling with -O2.
parse.c:
- 'prec' is only used when sokay == USEPREC and sokay = USEPREC
when 'prec' is assigned. Hence 'prec' is not used uninitialized,
initialize it to silence warning.
- The code involving 'nextpr' is hard to follow, but I belive
'nextpr' will not be used unless it is initialized.
Anyway, IF 'nextpr' is used uninitialized it is better to
get a consistant error (seg fault, when dereferencing a NULL pointer)
than potentially accessing some random memory.
The above changes makes hexdump WARNS=6 clean even when compiled with
-O2. Hence bump WARNS to keep it clean.

to the PR failed, because the line skipping function is actually called
from two places in the code to do quite different things (this should
be two functions probably): in a false .if to skip to the next line
beginning with a dot and to collect .for loops. In the seconds case we
should not skip comments, because they are actually harder to handle than
we need for the .if case and should defer this to the main code.
