from the code in
within both accelerators.
The C2H Compiler does not support external subfunctions. You must
locate the subfunction in the same source file as the accelerated function.
This is because, unlike the #include construct, a C external function
reference requires the presence of a linker. The C2H Compiler has no
linker.
