-+# SYNOPSIS
-+#
-+#   AX_ADD_FORTIFY_SOURCE
-+#
-+# DESCRIPTION
-+#
-+#   Check whether -D_FORTIFY_SOURCE=2 can be added to CPPFLAGS without macro
-+#   redefinition warnings, other cpp warnings or linker. Some distributions
-+#   (such as Ubuntu or Gentoo Linux) enable _FORTIFY_SOURCE globally in
-+#   their compilers, leading to unnecessary warnings in the form of
-+#
-+#     <command-line>:0:0: error: "_FORTIFY_SOURCE" redefined [-Werror]
-+#     <built-in>: note: this is the location of the previous definition
-+#
-+#   which is a problem if -Werror is enabled. This macro checks whether
-+#   _FORTIFY_SOURCE is already defined, and if not, adds -D_FORTIFY_SOURCE=2
-+#   to CPPFLAGS.
-+#
-+#   Newer mingw-w64 msys2 package comes with a bug in
-+#   headers-git-7.0.0.5546.d200317d-1. It broke -D_FORTIFY_SOURCE support,
-+#   and would need -lssp or -fstack-protector.  See
-+#   https://github.com/msys2/MINGW-packages/issues/5803. Try to actually
-+#   link it.
