Subject: Re: [GNU automake 1.16.5] test-suite 45 tests failed

Thanks, Karl.  automake-1.16.5/t/dist-vs-built-sources.dir/foo.c only has two lines:
#include "h.h"
int main (void) { printf ("%s\n", F); return 0; }

Also, automake-1.16.5/t/dist-vs-built-sources.sh only appears to be writing those two lines to foo.c and there is no inclusion of <stdio.h>.

Does that give you any clues?  Thx.

Erik
