* Makefile.maint (VC-tag): Define, so as to gpg-sign each release
tag, using the release version number as the message.
(vc-dist): Use $(VC-tag), rather than "$(VC) tag".

* Makefile.maint (my-distcheck): Don't *configure* with
restrictive CFLAGS ('-Werror -ansi -pedantic -Wno-long-long'),
since it ends up provoking errors in generation of inttypes.h
on an Ubuntu edgy-based system.  That leads to compilation
failure due to e.g., imaxabs redefinition.
Instead, configure with default CFLAGS, and compile the
package with restrictive CFLAGS.
