emerging rpm-4.0.4 w/ autoconf 2.35a produces this result:
cd . && autoconf
configure.in:1164: warning: AC_CONFIG_SUBDIRS: you should use literals
configure.in:20: error: do not use LIBOBJS directly, use AC_LIBOBJ (see section
`AC_LIBOBJ vs. LIBOBJS'
make: *** [configure] Error 1
!!! ERROR: The ebuild did not complete successfully.
!!! Function src_compile, Line -138, Exitcode 2
!!! (no error message)
Reading here:
http://sapi.vlsm.org/gnu/Manuals/autoconf-2.53/html_node/AC_LIBOBJ-vs.-LIBOBJS.html
Says that someone needs to patch the autoconf file to get it to work.
Also note that using autoconf 2.52d works fine.
