TMS320F280049C: Flash API header outdated?

If include Flash API like this:

#include "F021.h"

I get 

"/Applications/ti/C2000Ware_4_00_00_00/libraries/flash_api/f28004x/include/FlashAPI/Registers.h", line 65: fatal error #1965: cannot open source file "Registers_FMC_BE.h"

and when I look at the code in Registers.h I see that:

#if defined(_F2837xD) 

    #include "Registers_C28x.h"

#elif defined(_F2837xS)

    #include "Registers_C28x.h"

#elif defined(_F28004x)

    #include "Registers_C28x.h"

#elif defined(_C28X)

    #include "Registers_Concerto_C28x.h"

#elif defined(_CONCERTO)

    #include  "Registers_Concerto_Cortex.h"  

#elif defined(_LITTLE_ENDIAN)

    #include "Registers_FMC_LE.h"

#else    

    #include "Registers_FMC_BE.h"

#endif

So the reason for the error is that _F28004x  is not defined.

If I add:

#define _F28004x

before the include, then it compiles and seems to work.

Am I missing something or is the header out of synch with C compiler pre-defined stuff or how should this be handled in a canonical way?
