Hello, As one can't find string "distcheck" in GCS it looks like it wasn't GCS which constitutes support and usage of `distcheck' target. Maybe it is POSIX, or UNIX.
I wonder if recipe to build `distcheck' target as compiled by automake gets same form as John Calcote describes it in chapter 3 his Practitioner's Guide (2nd ed.). For one Makefile generated by autotools in one of my last projects I see building `check' target is included in `distcheck' recipe. If yes, all products prefixed with `check_' would be built also when `make distcheck' command is run. Please refer to automake manual ch. 3.3 paragraph 3rd from bottom. Regards k.d.
