I am suggesting this with zero actual experience writing pluggable
primitives, but, couldnt you
write just ONE pluggable primitive like so:

JasmineDLL methods


call: functionName with: argumentArray 

^self call: functionName with: argumentArray size: argumentArray size


call: functionName with: argumentArray size: argumentCount

"This primitive calls any of the functions in the Jasmine DLL.  Put the
arguments into
the argumentArray in the correct order"

<primitive syntax I don't know>

Then the C primitive would have code something like:

void * jasmineDLL_genericPrimitive (char * fname, void **argV, int argc)
{  if argc = 0 then return (void) & jasmineDLL_zeroArgFunction(fname);
   if argc = 1 then return (void) & jasmineDLL_oneArgFunction(fname,
argV);
..... etc to the maximum number of arguments in the library functions you
are stubbing to
}

......
void * jasmineDLL_twoArgFunction (char * fname, void **argV)
{   if strcmp(fname, "firstfunction") then return (void) &
firstfunction((int) *argv[0], (char *) argv[1]);
..... etc for each differnt 2 variable function
}

course with all the casting and stuff it'd be slower but it would work? 
the idea I mean,
not the exact code :)
