Is there any reason dlfcn.h is missing (at least on windows) and yet its functions and macros
are defined in tcclib.h, and that tcclib.h references it in a comment as if it were a file?
I also noticed RTLD_LOCAL was missing but it seems like
it should just be 0x000 since, according to oracle man pages,
local is the default option.
I see this on a windows build of 50abaae, which I'm using, and in windows mob.
