There is no planned limit.  I just tried a C function wrapper with 13
parameters, and it worked:

c-library xxx
\c #define test1(n1,n2,n3,n4,n5,n6,n7,n8,n9,n10,n11,n12,n13) 
n1+n2+n3+n4+n5+n6+n7+n8+n9+n10+n11+n12+n13
c-function test1 test1 n n n n n n n n n n n n n -- n
end-c-library

2 2 2 2 2 2 2 2 2 2 2 2 2 test1 .

We may be able to help more if you post the source code; the prototype
of the C function may also help.
