Odd TSE include error

I am including all the TSE Megacore function libraries in my code. When I go to include the header files I am able to add

# include "altera_avalon_tse.h"

# include "altera_avalon_tse_system_info.h"

# include "triple_speed_ethernet_regs.h"

# include "triple_speed_ethernet.h"

# include "altera_avalon_tse.h"

# include "altera_avalon_tse_system_info.h"

all successfully, but when I try to add

# include "ins_tse_mac.h"

# include "triple_speed_ethernet_iniche.h"

or

# include "iniche/ins_tse_mac.h"

# include "iniche/triple_speed_ethernet_iniche.h"

it errors and states that there is no such file or directory. I'm not sure how it's finding the other files but not these two. Any ideas?
