dnl Check if the compiler supports useful warning options. There's a few that
dnl we don't use, simply because they're too noisy:
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 $with_ext_const is "yes", add a check for -Wwrite-strings
