It is part of the gdb release.  In the sim/ppc directory, the text files
contain roughly 64,000 lines.  I don't recall how much of the infrastructure in
sim/common (50,000 lines) it uses, though my memory says that sim/ppc was
created before most of the sim/common framework was created, though it was the
model for sim/common.  The simulator uses BFD and opcodes as well.  The last
time I built it under Linux, it took 1.4M of text, 134M of static data.

The simulator requires prototypes and long long data types, and because of long
long, in general will not configure itself unless it is compiled by GCC.  Now
that C99 has long long, we probably should change the configure test.
