dnl This, $nw, is the list of warnings we disable.
nw=
nw="$nw -Waggregate-return" # anachronistic
nw="$nw -Wc++-compat" # We don't care about C++ compilers
nw="$nw -Wundef" # Warns on '#if GNULIB_FOO' etc in gnulib
nw="$nw -Wtraditional" # Warns on #elif which we use often
nw="$nw -Wcast-qual" # Too many warnings for now
nw="$nw -Wconversion" # Too many warnings for now
nw="$nw -Wsystem-headers" # Don't let system headers trigger warnings
nw="$nw -Wsign-conversion" # Not an error
nw="$nw -Wtraditional-conversion" # Don't care about pre-ANSI compilers
nw="$nw -Wpadded" # Our structs are not padded
nw="$nw -Wvla" # two warnings in mount.c
dnl things I might fix soon:
nw="$nw -Wmissing-format-attribute" # daemon.h's asprintf_nowarn
nw="$nw -Winline" # daemon.h's asprintf_nowarn
nw="$nw -Wshadow" # numerous, plus we're not unanimous
nw="$nw -Wvla" # Allow variable length arrays.
nw="$nw -Wshadow" # Not useful, as it applies to global vars
nw="$nw -Wunsafe-loop-optimizations" # just a warning that an optimization
# was not possible, safe to ignore
dnl things I might fix soon:
nw="$nw -Wpacked" # Allow attribute((packed)) on structs
nw="$nw -Wlong-long" # Allow long long since it's required
# by Python, Ruby and xstrtoll.
