Done, __NLDBL_REDIR/__NLDBL_REDIR2 macros.
As for the #defines for compilers without redirect or whatever other reasons
the redirections wouldn't work, I took a different approach which doesn't
clutter the headers - a small libnldbl_nonshared.a library which must
be inserted before -lm and/or -lc when building a program with
double == long double with non-redirect capable compiler.

I have tried to cleanup the libio hacks too.
