[Gm2] latest cvs checkin

[Gaius Mulley]

Hi,

I've checked in some modifications to gm2 which allow users
to access a few built-in constants and twenty seven C built-in
functions.

The file gm2/gm2-libs/Builtins.def serves to contain the list of
built-in functions which can be currently accessed.  Eventually these
built-ins will be utilised in the implementation of the iso modules,
for example a number of the functions in gm2-iso/LongMath.def will map
onto the trig built-in functions.

I've also updated the gm2.texi to document how and which
built-ins can be used.

enjoy,
Gaius
