Thanx, Jonathan, for your help... I seem to be getting somewhere now:

After looking into mips_exec.i, I got a view on the possible reason for the
"struct mallinfo redefinition" message. It seems that I had a few "#include
"malloc.h" statements throughout my application code. Since I didn't have a
malloc.h file in may eCos build (which I don't understand why), the compiler
(gcc) included it from its own include directory. This malloc.h was the
place of the first definition of "struct mallinfo". After I removed all
includes for <malloc.h> from my code, the compilation passed fine.

How come I have no malloc.h in my eCos build? Did I miss something in the
configuration file? How come "struct mallinfo" is defined in stdlib.h? Sorry
for all this questions... They're just jumping from the top of my mind...
;-)
