+Subject: [PATCH] Improve Configure detection of memmem() [perl #133760].
+
+Linux systems have memmem, but the header prototype is only visible if
+the C library, but didn't check if the correct prototype is available.
+This patch compiles & runs a test program that will fail if the prototype
+is needed but not available.
+
+This does not completely close [perl #133760].  The tests for strlcat()
+and strlcpy() may also need to be similarly changed.  Also, this patch
+does not change whether _GNU_SOURCE is defined or not.  Presumably that
+would be done separately in the linux hints file.

+
+This updates commit ca152fd8207cf53816b1407d5f54f6ea160a3ef8.
+Linux systems have memmem, but the prototype in <string.h> is only
+visible if __GNU_SOURCE is defined.  This version tests for both the
+prototype in <string.h> and the symbol in libc.  (Thanks to Tony C. for
+the suggestion.)  (For BSD systems, no extra define is needed.)

+Subject: [PATCH] Improve detection of memrchr, strlcat, and strlcpy.
+
+This is continuation of commit f8d82a1010 addressing [perl #133760].
+Linux systems using the musl C library have memmem, memrchr, strlcat, and
+strlcpy, but the prototypes are only visible if _GNU_SOURCE is defined.
+This patch makes Configure test both whether the prototype is visible
+and whether the C symbol is visible.
+
+Still to be done is automatically adding _GNU_SOURCE if the musl library
+is being used -- probably in hints/linux.sh.
