[RFC 00/20] Refactoring and modernizations in the depcomp script

[Stefano Lattarini]

OK, after putting this in the backburner for few months, I've decided to
finally go for some cleanup and refactoring in the 'depcomp' script.

Unfortunately, I can't test most of the less common depmodes first-hand,
since I lack access to the required compilers or systems.  So I'd really
like some feedback and real-world testing from possibly interested persons
(some of which I'm CC:ing, given their past contributions to the depcomp
script).  In particular, I'd appreciate if if anyone would able to run the
depcomp tests in the following compilers:

  - Microsoft Visual C/C++;

  - modern versions of the AIX, Tru64 and IRIX vendor C compilers;

  - the HP aCC (C++) and HP ia64 compilers;

  - the Portland Group C/C++ compiler;

  - the IBM C/C++ compilers (xlc/xlC);

  - The Intel C/C++ compilers, version 8.0 or later.

Any feedback would be very appreciated!

Regards,
  Stefano

P.S. Sorry for any delay in my replies, but I will be AFK in the
next few days.  I'll try to catch up after.
