http://cvs.openssl.org/chngview?cn=12493. Now all platform should
be operational, while SSE2 code pathes get engaged on ELF platforms
only.

is to have a placeholder to small routines, which can be written only
in assembler. In IA-32 case this includes processor capability
identification and access to Time-Stamp Counter. As discussed earlier
OPENSSL_ia32cap is introduced to control recently added SSE2 code
pathes (see docs/crypto/OPENSSL_ia32cap.pod). For the moment the
code is operational on ELF platforms only. I haven't checked it yet,
but I have all reasons to believe that Windows build should fail to
link too. I'll be looking into it shortly...

stop complaining about loss of precision, but explicit cast.

because "wrong" casts will either be optimized away or never performed.

libraries. Old .sl extension works just fine, but it .so which is default.

Win64 comes in two flavors, IA-64/Itanium and AMD64/Opteron. The
suggestion is to refer to former as WIN64I and latter - WIN64A

Apparently, the length *including* the NUL byte should be used.

Make a nicer comment, as we don't really know for sure that it's
really needed, and just want to play on the safe side.

with HP-UX offering 14 for NAME_MAX?

SIXTY_FOUR_BIT_LONG) were failing to pass 'cd test; make test_bn'.

Some code beautification.

Change the macro CP_THREAD_ACP to CP_ACP, because the latter is more
widely defined.

Add a conditional macro definition in case FindFirstFile and
FindNextFile aren't properly defined (might happen on WinCE).

Windows changes that detects if multibyte characters are available and
deals with them properly.

NUL-teminated at all times, and that we don't make unneeded calls to
free().

instead of local time.

I also used this opportunity to clean up some out-of-date targets and
re-group targets by OS.

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