To clarify, the error I've included stems from the gnulib's 'test-base64.c',
but same happens in other C projects which use gnulib's base64.c module, as in:

    $ make
    <...>
    source='lib/base64.c' object='lib/base64.o' libtool=no \
        DEPDIR=.deps depmode=tcc /bin/bash ./build-aux/depcomp \
        tcc -DLOCALEDIR=\"/usr/local/share/locale\" -DHAVE_CONFIG_H -I.  -Ilib 
-I./lib -Isrc -I./src   -g -c -o lib/base64.o lib/base64.c
