Hi list,

Sorry if this is the wrong list to post this and feel free to point me
out a more correct one.  Please Cc: me in your replies, I am not
subscribed to this list.

I'm usually developping on FreeBSD but I wanted to test my application
on NetBSD as well.  The good news is they're both using almost the
same makefile framework.

I used to compile my source using WARNS=6 on FreeBSD and the latter
fails on NetBSD 4.0_BETA2:

% #   compile  poolexecutor/zthreadstub.o
% c++ -O2 -Wall -Wpointer-arith -Wno-sign-compare -Wreturn-type -Wswitch -Wshadow -Wcast-qual -Wwrite-strings -Wextra -Wno-unused-parameter -std=gnu99 -Werror   -Wabi -Wold-style-cast -Wctor-dtor-privacy -Wnon-virtual-dtor -Wreorder  -Wno-deprecated -Wno-non-template-friend  -Woverloaded-virtual -Wno-pmf-conversions -Wsign-promo -Wsynth     -c    zthreadstub.cc
% cc1plus: warnings being treated as errors
% cc1plus: warning: command line option "-std=gnu99" is valid for C/ObjC but not for C++
% *** Error code 1


The fix is trivial and the patch is following:
