Hi William,

I can't find _initialize_arch_tdep in the GDB code base, so I presume it 
is the init function in your private -tdep.c file that you want GDB to 

The only reason I see for your function not ending up in init.c is that 
doesn't respect the regex that looks for init functions:

1855         @-for f in $(INIT_FILES); do \
1856             sed -n -e 's/^_initialize_\([a-z_0-9A-Z]*\).*/\1/p' \
1857                 $(srcdir)/$$f 2>/dev/null; \

The function name but start at the beginning of the line and start with 
"_initialize_".  That's the only guess I can make with the provided
