My understanding is the bit about "it does not include the work's
System Libraries, or general-purpose tools or generally available free
programs which are used unmodified" allows using the latest version of
autoconf and/or individual autoconf files since it's a generally
available free program that's being used unmodified.  But I'm not a
lawyer, so my understanding isn't worth beans..

I'd be surprised if they changed the wording of the GPL.  I wouldn't
expect more than an additional FAQ entry to clarify matters.  In any
case, please let me know their answer.

I don't remember if I tried it after updating config.guess &
config.sub or not.  And it turns out I shouldn't be using
AC_CANONICAL_SYSTEM anyway - see
https://www.gnu.org/software/autoconf/manual/autoconf-2.69/html_node/Obsolete-Macros.html

*sigh* I need to keep better notes.  What I added was
AC_CONFIG_HEADER([config.h])
dnl LR * AC_CANONICAL_HOST
dnl LR * ac-canonical-host does not set up a compiler toolchain
dnl LR * as in, it does not support cross-compiling???

and I don't remember where I got the idea it doesn't set up a compiler
toolchain.

./configure --build=i686-pc-cygwin --host=i686-w64-mingw32  --enable-mingw32

I don't have much confidence in software built on guesses & cargo-cult
programming (which is what I did).  So I'd like to use
privoxy-regression-test.pl to check as much as I can.  hrmm.. yes, I
should have said that before asking for suggestions on which
parameters to use.  Sorry :(

looks like - at least it's the same number of failures:

$ ./run_regression_test
