1914 dnl CF_GCC_WARNINGS version: 29 updated: 2012/06/16 14:55:39
1916 dnl Check if the compiler supports useful warning options. There's a few that
1917 dnl we don't use, simply because they're too noisy:
1919 dnl -Wconversion (useful in older versions of gcc, but not in gcc 2.7.x)
1920 dnl -Wredundant-decls (system headers make this too noisy)
1921 dnl -Wtraditional (combines too many unrelated messages, only a few useful)
1922 dnl -Wwrite-strings (too noisy, but should review occasionally). This
1923 dnl is enabled for ncurses using "--enable-const".
1927 dnl $1 is an optional list of gcc warning flags that a particular
1928 dnl application might want to use, e.g., "no-unused" for
1931 dnl If $with_ext_const is "yes", add a check for -Wwrite-strings
