+# SYNOPSIS
+#
+#   MHD_FIND_ADD_CC_LDFLAG([VARIABLE-TO-EXTEND],
+#                         [FLAG1-TO-TEST], [FLAG2-TO-TEST], ...)
+#
+# DESCRIPTION
+#
+#   This macro checks whether the specific compiler flags are supported.
+#   The flags are checked one-by-one. The checking is stopped when the first
+#   supported flag found.
+#   The checks are performing by appending FLAGx-TO-TEST to the value of
+#   VARIABLE-TO-EXTEND (LDFLAGS if not specified), then prepending result to
+#   LDFLAGS (unless VARIABLE-TO-EXTEND is LDFLAGS), and then performing compile
+#   and link test. If test succeed without warnings, then the flag is added to
+#   VARIABLE-TO-EXTEND and next flags are not checked. If compile-link cycle
+#   cannot be performed without warning with all tested flags, no flag is
+#   added to the VARIABLE-TO-EXTEND.
+#
+#   Example usage:
+#
+#     MHD_CHECK_CC_LDFLAG([additional_LDFLAGS],
+#                        [-Wl,--strip-all], [-Wl,--strip-debug])
+#
+#   Note: Unlike others MHD_CHECK_*CC_LDFLAG* macro, this macro uses another
+#   order of parameters.
