Autoconf was failing to detect install-sh at the top level and needed
some explicit directions. It also wants config.guess and config.sub to
be provided too.
A few other macros have also been updated.
Functions in memory.c tracked and instrumented memory allocation. This
mechanism logged information to a text file and also added a 16KB guard
area to every allocation. Neither of these are desirable in a multi-
user environment, so the whole memory tracking subsystem has been
disabled.
The behavior can be enabled with a configure flag, but it would be a
better idea to use Valgrind to deal with memory bugs.
