config.guess: unrecognizable system type

[Daryush Mehta]

Hi

I received the following error:

If the version you run (./config.guess) is already up to date, please
send the following data and any information you think might be
pertinent to <address@hidden> in order to provide the needed
information to handle your system.

config.guess timestamp = 2001-09-04

uname -m = x86_64
uname -r = 2.5.2(0.297/5/3)
uname -s = CYGWIN_NT-10.0
uname -v = 2016-06-23 14:29

/usr/bin/uname -p = unknown

configure: error: cannot guess build type; you must specify one

Note that when I include the newest .guess and .sub files, .sub does not run:

...
checking return type of signal handlers... void
checking for vprintf... yes
checking for _doprnt... no
checking for floor... yes
checking for gettimeofday... yes
checking for memmove... yes
checking for memset... yes
checking for modf... yes
checking for pow... yes
checking for socket... yes
checking for sqrt... yes
checking for strchr... yes
checking for strcspn... yes
checking for strrchr... yes
checking for strspn... yes
checking for strstr... yes
checking for strtol... yes
configure: error: cannot run /bin/sh ./config.sub

Let me know if I can provide further information.

Thanks
