will either be optimized away or never performed. The trouble is that
compiler first parses code, then optimizes, not both at once...

avoid use of prohibited MD5 algorithm.

instead of local time.

we were mislead by _MSC_VER macro, which is defined by *all* Windows
Microsoft compilers.

compilers, e.g. DEC C.

_stricmp() on that platform, use the appropriate header file for it,
<string.h>.
o_str.h: we only want to get size_t, which is defined in <stddef.h>.

Philippe Bougeret <philippe.bougeret@freesbee.fr> notified us about Windows
not having a <strings.h>

Add a note as to how these functions do not always return the key size, and
how one can deal with that.

Makefiles where this was fixed by commenting away code, change it to
check for an empty EXHEADER instead, so we have less hassle in a
future where EXHEADER changes.
