| Look at the patch. Use -fno-builtin to silence the warning.

gcc isn't the only compiler, but -fno-builtin is not universally
available.  Blindly setting CFLAGS to include options that are not
globally portable is insufficient; the patch must also make sure that the
options are supported by the current compiler.  That's where things get
tricky, which is why I haven't bothered to try patching it.  It also means
that any patch to get it working will probably require copyright
assignment; would you be interested in starting that process?

| without. However some tests fails in both cases.

Which tests?  Can you post the testsuite.log from an unpatched run?
