I'm compiling cpython using cygwin with the latest gcc on a Microsoft Surface Book under Windows 10.
I downloaded and installed the latest config.guess and config.sub
$ ./configure
checking build system type... ./config.guess: unable to guess
system type
This script (version 2017-02-07), has failed to recognize the
operating system you are using. If your script is old, overwrite
config.guess and config.sub with the latest versions from:
http://git.savannah.gnu.org/gitweb/?p=config.git;a=blob_plain;f=config.guess
and
http://git.savannah.gnu.org/gitweb/?p=config.git;a=blob_plain;f=config.sub
If ./config.guess has already been updated, send the following
data and any
information you think might be pertinent to address@hidden
to
provide the necessary information to handle your system.
