-dnl @synopsis AX_CFLAGS_NO_WRITABLE_STRINGS [(shellvar [,default, [A/NA]])]
-dnl
-dnl Try to find a compiler option that makes all stringliteral
-dnl readonly.
-dnl
-dnl The sanity check is done by looking at string.h which has a set of
-dnl strcpy definitions that should be defined with const-modifiers to
-dnl not emit a warning in all so many places.
-dnl
-dnl For the GNU CC compiler it will be -fno-writable-strings
-dnl -Wwrite-strings The result is added to the shellvar being CFLAGS by
-dnl default.
-dnl
-dnl DEFAULTS:
-dnl
-dnl - $1 shell-variable-to-add-to : CFLAGS
-dnl - $2 add-value-if-not-found : nothing
-dnl - $3 action-if-found : add value to shellvariable
-dnl - $4 action-if-not-found : nothing
