But then HAVE_GETPAGESIZE probably should not succeed spuriously because of an implicit function declaration.
I hope that the only platforms that should use that old getpagesize code, are platforms so old that implicit function declarations work, which means we are OK there. If I'm wrong I'd like to know what platform is a counterexample before further fiddling with this ancient cruft.
I still suspect there is something peculiar to libgtop that triggers this, such as some late -D_XOPEN_SOURCE somewhere, or conditional execution of the HAVE_UNISTD_H check.
Matt reported in <https://bugs.gentoo.org/show_bug.cgi?id=898816#c7> that the Autoconf patches fix the issue in libgtop, whatever it is.
