Leading underscores (was: Re: Deprecation)

#defines should not start with an underscore. C standards say this is reserved (for system headers !?) and some static analyzers complain about it.

Note that Nettle has violated this rule since the very beginnings. E.g,

#define _MD5_DIGEST_LENGTH 4

has been in md5.h since the initial commit (back in April 2001, around midnight). I haven't seen any reports about this causing problems.

I agree it's not quite right, and maybe we should clean this up at some point, replacing the leading underscore by nettle_internal_ (or maybe trailing underscore or nettle__ (double underscore). But not now.

Which static analyzers complain?
