Defintions of macros similar to _XOPEN_SOURCE belong in command line
or in worst case prior first #include directive in source. As for
macros is was allegedly controlling. One can argue that we are
probably better off demanding S_IS* macros but there are systems
that just don't comply, hence this compromise solution...

The use of the uninitialized buffer in the RNG has no real security

This was done by the following
        find . -name '*.[ch]' | /tmp/pl
where /tmp/pl is the following three-line script:
        print unless $. == 1 && m@/\* .*\.[ch] \*/@;
        close ARGV if eof; # Close file to reset $.

And then some hand-editing of other files.

Use setbuf(fp, NULL) instead of setvbuf().  This removes some

Because of a missing include <fcntl.h> we don't have O_CREATE and don't create
the file with open() using mode 0600 but fall back to using fopen() with the
default umask followed by a chmod().

doule as last argument.

let's check for those macros, and if they aren't defined, let's assume
there aren't Unixly devices on this platform.

specially if it is.
Add a few OpenBSD-specific cases.
This is part of a large change submitted by Markus Friedl <markus@openbsd.org>

I've covered all the memset()s I felt safe modifying, but may have missed some.

For those, unless the environment variables RANDFILE or HOME are
defined (the default case!), RAND_file_name() will return NULL.
This change adds a default HOME for those platforms.

To add a default HOME for any platform, just define DEFAULT_HOME in
the proper place, wrapped in appropriate #ifdef..#endif, in e_os.h.

inconsistencies)

compared to it has the type size_t.  Included the needed headers to
make that happen.
