dnl
dnl -Wconversion (useful in older versions of gcc, but not in gcc 2.7.x)
dnl -Wredundant-decls (system headers make this too noisy)
dnl -Wtraditional (combines too many unrelated messages, only a few useful)
dnl -Wwrite-strings (too noisy, but should review occasionally). This
dnl is enabled for ncurses using "--enable-const".
dnl -pedantic
dnl
dnl Parameter:
dnl $1 is an optional list of gcc warning flags that a particular
dnl application might want to use, e.g., "no-unused" for
dnl -Wno-unused
dnl Special:

dnl If we're installing into a subdirectory of /usr/include, etc., we should
dnl prepend the subdirectory's name to the "#include" paths. It won't hurt
dnl anything, and will make it more standardized. It's awkward to decide this
dnl at configuration because of quoting, so we'll simply make all headers
dnl installed via a script that can do the right thing.
rm -f headers.sed headers.sh

# This shell script is generated by the 'configure' script. It is invoked in a
