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

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.

This compiles and runs on Linux, and external applications have no
problems with it.  The definite test will be to build this on VMS.

like Malloc, Realloc and especially Free conflict with already existing names
on some operating systems or other packages.  That is reason enough to change
the names of the OpenSSL memory allocation macros to something that has a
better chance of being unique, like prepending them with OPENSSL_.

This change includes all the name changes needed throughout all C files.

This is superfluous now that we don't have to avoid creating
multiple versions of the file on VMS (because older versions
are now deleted).

couldn't be opened.

(they don't really exist before version 7), so that solution was toast.
Instead, let's do it the way it's done on Unix, but then remove older
versions of the file.

That new mechanism *may* fail for some unixly formated file spec,
although I wouldn't worry too much about it.

(actually, much more is needed, like a real config script)

this is what we now use to read $RANDFILE / $HOME/.rnd.
(Previously, after 'cat'ting lots of stuff into .rnd
only the first MB would be looked at.)

Bugfix for apps/enc.c: Continue if RAND_pseudo_bytes returns 0
(only -1 is an error).

opening the output file with "wb" to truncate it except on VMS
(where the file now keeps its original length because it is opened
with "rb+" -- does VMS have ftruncate?)

(we're now using fopen(..., "rb+") instead of fopen(..., "wb"),
so the file is not truncated automatically).

returns int (1 = ok, 0 = not seeded). New function RAND_add() is the
same as RAND_seed() but takes an estimate of the entropy as an additional
argument.

some utilities that should have used RANDFILE did not,
and -rand handling was broken except in genrsa.

This will soon be complemented with MacOS specific source code files and
INSTALL.MacOS.

I (Andy) have decided to get rid of a number of #include <sys/types.h>.
I've verified it's ok (both by examining /usr/include/*.h and compiling)
on a number of Unix platforms. Unfortunately I don't have Windows box
to verify this on. I really appreciate if somebody could try to compile
it and contact me a.s.a.p. in case a problem occurs.

in cryptlib.h (which is often included as "../cryptlib.h"), then the
question remains relative to which directory this is to be interpreted.
gcc went one further directory up, as intended; but makedepend thinks
differently, and so probably do some C compilers.  So the ../ must go away;
thus e_os.h goes back into include/openssl (but I now use
#include "openssl/e_os.h" instead of <openssl/e_os.h> to make the point) --
and we have another huge bunch of dependency changes.  Argh.

There were problems with putting e_os.h just into the top directory,
because the test programs are compiled within test/ in the "standard"
case in in their original directories in the makefile.one case;
and in the latter symlinks may not be available.
