uClibc misc. cosmetics (fwd)

[Peter S. Mazinger]

Summary of a private discussion about libc-internal.h (see attached)

gcc does
#define _LIBC
#include <iirc locale.h>
in libstdc++

Once I removed libc-internal.h from target, and it failed because
features.h includes it if _LIBC is defined

imho gcc shouldn't use _LIBC, but that is gcc's problem
including though libc-internal.h produces errors, so I want this file 
removed from target completely

possibilities:
a. install a modified features.h that does not include libc-internal.h, 
removing libc-internal.h from target
b. install a dummy libc-internal.h instead of the internal one

Votes?

Peter

I'll think a bit more about it.
