+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

+dnl CF_XOPEN_SOURCE version: 25 updated: 2007/01/29 18:36:38
+dnl ---------------
+dnl Try to get _XOPEN_SOURCE defined properly that we can use POSIX functions,
+dnl or adapt to the vendor's definitions to get equivalent functionality,
+dnl without losing the common non-POSIX features.
+dnl
+dnl Parameters:
+dnl $1 is the nominal value for _XOPEN_SOURCE
+dnl $2 is the nominal value for _POSIX_C_SOURCE
