Right.  I've run gcj code on a number of different simulator targets
recently.  It sounds like Antonio needs to configure things properly in
gcconfig.h.   I think mmap is used to get memory for some unix targets.  For
embedded target's we've simulated we simply define our own "sbrk" which
returns memory from a statically allocated heap.  Search for ECOS in
os-dep.c.
