When you tried to use whichsys.c32, could you please provide:
A_ the path for your Current Working Directory?
B_ the path for the cfg file where you have the relevant whichsys.c32 
boot entry?
C_ the path of the boot loader, and which one you used in your tests 
(ldlinux.sys, isolinux.bin)?
D_ the path where you have ldlinux.c32?
E_ the path where you have libcom32.c32?

Maybe with that additional info the issue can be replicated.

Thank you and Regards,
Ady.
