ok, so I may be a little "dense" due to decompression from the flight, 
but I need a bit more explanation of the differences between 
CPPEXTERN_NEW_WITH_GIMME and *_WITH_ARGS:  what did you mean by 
"manual" type-checking?  I've been looking at the different usages 
throughout the other code, but it seems to be somewhat differently used 
in each circumstance...

...If pd only allows 5 typechecked arguments, does that mean I can't 
make a CPPEXTERN_NEW_WITH_SIX_ARGS?

...If I use the GIMME method, does that limit the number of inlets I 
can deal with?  Fr'instance, for this current wrapper 
"GEMglProgramEnvParameter4dARB", I'd like to have seperate inlets for 
not only target and index, but also x, y, z, w:  after all, there is 
another call "GEMglProgramEnvParameter4dvARB" that would accept target, 
index, and a vector of x,y,z,w (and therefore only need 3 inlets)...I 
ask this because it seems that some GIMME-based externs use a "params" 
message, and I don't want to require non-vector accepting GL calls to 
accept vectors...

thanx,
