The upcoming Cygwin 1.7.0 release adds so many APIs and improves so much functionality that it probably deserves a separate designation in config.guess. For reference, notice the size of the most recent beta announcement: http://cygwin.com/ml/cygwin-announce/2009-02/msg00018.html
For an example of a script in the wild that could take advantage of a separate designation, look at line 757 in the following, which sets some guesses when cross-compiling to cygwin: http://git.savannah.gnu.org/gitweb/?p=gnulib.git;a=blob;f=m4/printf.m4;h=4207ace;hb=f7beddb In the example, cygwin 1.5.x lacks the printf grouping flag, but cygwin 1.7.0 provides it. The patch deliberately avoids the extra forking of `echo | sed`, since that is inherently slower on cygwin. Here's the 'uname -r' output (${UNAME_RELEASE}) between cygwin 1.5.x and cygwin 1.7.0, such that this patch keeps i686-pc-cygwin for 1.5.x, but uses i686-pc-cygwin1.7 for 1.7.0. 1.5.25(0.156/4/2) 1.7.0(0.200/5/3) Most decent scripts out there already use *-*-cygwin* in shell case statements that depend on the platform name, so they will continue to match *-*-cygwin1.7. 2009-02-26 Eric Blake <e...@byu.net> * config.guess (*-*-cygwin1.7): Add new designation for cygwin 1.7.0, distinct from 1.5.x. -- Don't work too hard, make some time for fun as well! Eric Blake e...@byu.net
