Using autoconf 2.62 on my primary test system I am getting:
configure:26081: error: possibly undefined macro: AS_VAR_IF
Indeed use of AS_VAR_IF appears relatively new, and it seems this may be similar to AS_VAR_APPEND where we have the following in configure.ac:
dnl autoconf versions before 2.63b don't have AS_VAR_APPEND m4_ifdef([AS_VAR_APPEND],,[as_fn_append () { eval $[1]=$$[1]$[2]; } AC_DEFUN([AS_VAR_APPEND],[as_fn_append $1 $2])])dnl
I assume we need something similar here, too? I am really far from an autoconf hacker -- is this something one of you could look into?

Indeed this was specific to autoconf 2.62 vs 2.64. Running autoconfig 2.67 on said tester now, everything works smoothly.
