You don't need it,  I do.  In general,  it's not necessary to use 
but it's there because the code generation needs to remain "live" in
order to be an asset but is also time consuming for people doing
repetitive installs to fix problems.   Prior to Python-2.4 and VC.NET,
--gen_code had meaning on win32 because VC6.0 didn't fully support
UInt64.  Everywhere else,  the CVS'ed C source just works.

Sure.  I would say just don't worry about it unless you're building on
win32 from source using VC6.0.

No,  I think that's been there since 1.2.1 or so.  It's an artifact of
user submitted fixes to the linear algebra package which I accepted as-
is because they were submitted by someone who both knew enough
technically and had enough idealism to make the effort.
