You compiler is providing 32-bit doubles. You need 64-bit doubles in
order to build the eCos math library. There's a patch available for the
KPIT v0401 tools which may help:

Perhaps your toolchain does not provide the appropriate multilib support
for "-mh -mint32"? You can check using:
$ h8300-elf-gcc -print-multi-lib
Note that most of the eCos community is using GCC 4.3.2 so you may well
discover a few compiler warnings and other issues if you build with GCC
4.4.0.
