Re: [lmi] Re: To configure wx-2.6.2

[Greg Chicares]

As part of this scheduled task:
  "Automate installation for compiling in ms windows"
I'm reworking the procedure we use to build wx. It mostly follows
this old posting, which I'll now bring up to date so that we have
the rationale in one place.

That should be in CPPFLAGS, not CXXFLAGS.

Auditing this today, I find that we've been using
  --enable-debug_info
instead of
  --enable-debug
in production; I believe we should use the latter instead,
after careful testing.

We've also been using
  --disable-vararg_macros
which I find documented only off the list, in a message whose
relevant portion I'll copy here for completeness:

[Vadim did that with '--disable-vararg_macros', thanks]
