  can i find it on the svn?

I use
#define PD_FLOATTYPE double
before including m_pd.h
in an external.

it compiles but it occurred to me that i have to recompile Pd with the 
same definition to test it,
that was not what i searched cause i prefer to use "standard" pd and to 
add externals.

with the [tabread_double] paradigm, it'll work regarding any floattype 
of the Pd used.
otoh, im' not sure i can manage transparent operation keeping the 
precision i want, i mean building an abstraction that takes as an input 
a float that can be bigger than 2^24 and that automaticcaly use 
tabread_double or tabwrite_double the good way.
Maybe i'll need to do a special + - or % / or >> << to achieve that.
mmm tricky
