Sigh, I was certainly not firing on all cylinders last night.
That *is* the spelling of the message in 7.1 and before --- see
catalog/pg_proc.c.  Are you certain that you recompiled with the new
setting of FUNC_MAX_ARGS?  Unless you did configure --enable-depend,
config.h changes generally require "make clean" before "make all" to
ensure that the changes propagate.
