The SDB/coff debug info support is broken.  This is easy to see by 
comparing against an older toolchain with working SDB/coff debug info, 
or by looking at the assembler sources for this debug info format.  The 
.def pseudo-op takes only one argument, not two.

This is an obsolete debug info format.  You can't describe C++, Ada, or 
Java with it.  You can't even fully describe ISO C89, it only supports 
those types that are in K&R C.

The best solution is to stop using this obsolete format.  Use stabs in 
coff instead.  You can do this by configuring with --with-stabs, or by 
modifying the h8300.h port to set PREFERRED_DEBUGGING_TYPE to DBX_DEBUG.

If you want it fixed, then debug gcc to figure out what is wrong, or 
submit a bug report, and hope someone looks at it.
