Attempt to follow these instruction and you will at best end up with a bunch
of comiler error messages, at worst, a ruined BDI-4.xx install (which
fortunately can be recovered from by re-installing the emc package)'

You do NOT have to log in as root to compile any code. Only the final
installation requires root permissions.

On a BDI-2.xx install, this would work as long as the (unmentioned) previous
steps had been taken. For a BDI-4 install, the process is a simple
"./configure && make" as it is with ALL the emc2 branches.

Sorry Keith, but it is doomed to failure, aside from the completely revamped
build system, there are a number of incompatabilities in the source code
between the (depreciated) EMC1 tree and the current emc2 tree.

Yup, probably the best place to ask about any emc2 related questions.

(as a side note) Many bugs were fixed in the interpreter in the migration to
the emc2 tree, some identified by Keith, others from a general review of the
code. G92 now acts in full accordance with Tom Kramer's original
documentation.
