Something which occurred to me when looking at the magic whistle code.
It's behavior can vary depending upon whether pline()/You()/&c has
been called and that is detected by checking whether pline() has reset
iflags.last_msg. Change the debugpline() mechanism to prevent it from
interfering with that.
There is no longer any compiler reason to disable nhUse - remove
nhUse's conditional definition.
Update the nhUse definition to "use" a variable without it needing
to be an integer.
This change removes some gcc compiler unused variable and parameter
warnings.
I upgraded from OSX 10.5.8 via 10.6.3 to 10.6.8, plus Xcode to whatever
version was on the 10.6 dvd, and ended up with a more recent version of
gcc that is configured to use 64 bit longs and 64 bit pointers (by
default; presumably that can be changed if necessary). It triggered
several warnings about converting int to pointer of different size or
vice versa even when explicit casts were in use, and a couple of other
things.
With DEBUG suppressed, I started getting
16 warning: empty body in an if-statement
and 2 warning: empty body in an else-statement
from gcc.
Using braces for an empty block instead of just ';' avoids the warning:
if (foo)
debugpline("foo");
is bad,
if (bar) {
debugpline("bar");
}
is good. ;-)
The changes to lint.h are just precautionary.

I did my best to exempt some of the bigger aligned blocks from the reformatting
using the /* clang-format off */ and /* clang-format on */ tags. Probably some
that shouldn't have been formatted were anyway; if you encounter them, please
fix.
The clang-format tags were left in on the basis that it's much easier to prune
those out later than to put them back in, and it means that, modulo my custom
version of clang-format, I should be able to run clang-format on the source tree
again without changing anything, now that Pat has fixed the VA_DECL issues.
modified files: include/hack.h, src/decl.c, sys/unix/Makefile.src
Groundwork for cleaning up the X11 sources, where gcc with the option
settings specified in the OSX hints file currently generates close to
400 warnings for win/X11/*.c.
lint.h is included by hack.h, and I've moved the debugpline stuff from
the latter to the former to hide it better. (By rights it belongs in
debug.h or something of the sort, but I didn't want to go that far.)
Makefile and project dependencies need to catch up.
nhStr() hides a cast to char *, and is intended to by used on string
literals where it isn't feasible to maintain the 'const' attribute.
(A pernicious problem with X11 code, where the include situation can
become very convoluted, and many, MANY string literals are hidden
behind macros to look like keyword-type tokens.)
nhUse() can be used to force a fake usage on something which triggers
an unused parameter warning. There are a 6 or 8 or 10 places in the
core code where that applies, but so far I have't touched any of them.
There's a tradeoff since it will result in some worthless code being
generated and executed, but is much simpler than tacking on compiler-
specific workarounds like '#pragma unused' or gcc's __attribute__ hack.
