+
+Compiling mhash-0.9.9.9 on platforms (like AIX) without GNU libc compatible malloc leads to undefined symbol rpl_malloc
+when linking the in-mhash executables drver, frag_test, rest_test, hmac_test, keygen_test.
+
+Reason is that configure.in still contains AC_FUNC_MALLOC, detecting need
+to "#define malloc rpl_malloc", while mhash does not provide a rpl_malloc implementation.
+
+As the only use of malloc() in lib/stdfns.c does not rely on GNU libc
+compatible malloc actually, there is no need to check for one.
