Let's see if I can help you a bit:

There was, a long time ago, the one original AT&T UNIX. However, it's long been discontinued, with rights going through various hands (see the current Novell vs. SCO squabble). Sometime around the late 1970s, two different systems started to emerge: System V, and the Berkley Standard Distribution. Current Unices are based on those two. For a complete overview, Wikipedia has a pretty good article.
If by "high-end" you mean "expensive closed-source company produced", you won't be able to buy these alone. Those usually come bundled with hardware, and aren't available without it (AIX, HP-UX, and MacOS X are examples of that).
Deciding on what UNIX to use depends on what you want to do. If you want to develop in a wide range of languages, or using the most current hardware, I'd suggest Linux. If you want a stable system (both in terms of run-time and system behaviour), I'd suggest *BSD or OpenSolaris
The hardware modern Intel-based Macs use is pretty much completely PC hardware, so it won't make any difference on stability. But I suggest setting up the new system on different hardware, since it won't be as much trouble should you need to re-install.

Does the assembler output differ between operating systems ?

The assembly code generated by assembler, from a C-source code depends on the CPU architecture underlying it, eg x-86 . Then does the assembler output of a simple C-source code (containing common function-calls of both windows and linux) differ between Operating Systems ?

NAME

       README.macos - Perl under Mac OS (Classic)

SYNOPSIS

       This document briefly describes perl under Mac OS (Classic).  If you are running perl under Mac OS X, you don't want to be here (unless you
       are in the Classic environment under Mac OS X).

       When we say "Mac OS" below, we mean Mac OS 7, 8, and 9, and not Mac OS X.

DESCRIPTION

       The latest perl source itself builds on Mac OS, with some additional pieces. Support for Mac OS is now in the perl core, and MacPerl is
       kept in close sync with regular perl releases.

       To build perl for Mac OS (as an MPW tool), you will need the addition of the macos subdirectory, distributed separately.  It includes extra
       source files, config files, and make files.  It also includes extra Mac-specific modules.

       To build the MacPerl application, you will also need the macperl directory, which includes the source files for creating the application
       itself.

       All of this is available from the development site, via HTTP (in the MacPerl Installer, which includes all the source and binaries) and
       anonymous CVS.

	       http://dev.macperl.org/

       The source is also in the main perl repository in the macperl branch (the 5.6 source is in the maint-5.6/macperl branch).

       You will also need compilers and libraries, all of them freely available.  These are linked to from the SourceForge site. Go that site for
       all things having to do with MacPerl development.

       MacPerl 5.6.1 and later are supported on Mac OS 8.1 and later, for 68040 and PowerPC architectures.  The MPW tool may be used on Mac OS
       7.5.5 and 68030 computers.

       MacPerl 5.2.0r4 is also available, on the CPAN and on SourceForge.  It is based on perl 5.004, and works with Mac OS 7.5.5 and 68030 com-
       puters.

AUTHOR

       perl was ported to Mac OS by Matthias Neeracher <neeracher@mac.com>.  It is currently maintained by Chris Nandor <pudge@pobox.com>.
