* Update maintainers build process; remove GNUmakefile. Require builders to
run automake && autoreconf by hand.
* Use AC_SUBST_FILE to get the maintMakefile included, rather than GNU
make's include directive, which conflicts with automake 1.4's include
directive.
* Check for a libc version of GNU glob and, if found, don't use the local
glob headers.
* Fix a bug in OpenVMS archive handling.
* Fix a bug in VMS siglist processing.
