fetchmail 5.7.4, like fetchmail 5.7.2, generates a Makefile that
contains dependencies on the nonexistent aclocal.m4. I don't really see
why I should have to install GNU autoconf just to build fetchmail; no
other software I've seen that uses autoconf to generate "configure"
requires that autoconf be installed in order to run "configure" or build
the software.
fetchmail 5.7.4 also seems dead-set on trying to build with inet6
support even if I pass the configure option "--disable-inet6". By
default it tries to enable inet6 support; with "--disable-inet6"
configure bonks out with:
checking for getaddrinfo in -linet6... no
configure: cannot find proper glibc version or libinet6,
which is required for IPv6 support.
I am running fetchmail on a libc5 system; up until now that hasn't been
a problem.
