"Proper" means "compiles and passes test." Versioning is broken (I think).

COFF and a.out targets [similar to ELF targets]. You might notice some
rudementary support for shared mingw builds under cygwin. It works (it
produces cryptoeay32.dll and ssleay32.dll with everything exported by
name), but it's primarily for testing/debugging purposes, at least for
now...

available compiler versions generated bogus machine code trying to
compile new crypto/des/cfb_enc.c. Secondly, 8th version defines
__GNUC__ macro, but fails to compile *some* inline assembler correctly.
Note that all versions of icc implement MSC-like _lrot[rl] intrinsic,
which is used now instead of offensive asm. Finally, unnecessary linker
dependencies are eliminated. Most notably dependency from libirc.a
caused trouble at application start-up, if libcrypto.so is linked with
-Bsymbolic (which it is).

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

with "OPENSSL_" to avoid conflicts with other packages and by making
sure e_os2.h will cover all platform-specific cases together with
opensslconf.h.

I've checked fairly well that nothing breaks with this (apart from
external software that will adapt if they have used something like
NO_KRB5), but I can't guarantee it completely, so a review of this
change would be a good thing.
