Hello Bruno,

Thanks for the changes you applied.  As usual, you show much more
diligence in fixing things.  :-)

Ouch, sorry for the bad ChangeLog entry.

To supply a prototype for strcpy which is used in the test.
Is it safe for the test to not include string.h (only stdlib.h is
currently included) and declare strcpy manually, or could that
conflict with a builtin?  Since gnulib assumes C89 there should be
no problem with stdlib.h providing a strcpy prototype, right?

Cheers,
Ralf
