I added the define in the enclosed patch and also re-added the
__IEEE_LITTLE_ENDIAN define.

Alain, can you please verify that the #define _JBLEN 40 is correct? I
was making a guess based on your code. It seems you needed to reserve
0xA0  bytes, and based on the assumption that a bfin long is 4 bytes I
came the result of 40.

The whole tool chain now builds for HIXS and produces code that will
not offend AC_PROG_CC.
