$OSTYPE - Aaaaaaaaaaaaaaargh !

Hello,

with the lastest version of the bash the content of $OSTYPE has changed from "cygwin" to "cygwin32" again without further notice. Since I used this entry to detect the old B20.1 from the new Cygnus V1.1 I have now a lot of broken scripts and makefiles that have to run on both versions. This drives me really crazy!

So is there any *reliable* method to detect the version of Cygwin from a script ?

Greetings,
Jörg

Yep.

use the source to find out.

The 's' was added very recently to mean snapshot.

No.  The best place to get config.guess and config.sub is from the config
directory found at ftp.gnu.org or a mirror.

It seems that this version of bash was compiled with the config.guess file
included in the bash distribution. This config.guess stills responds with
i686-pc-cygwin32

use uname; using bash is a bad idea because bash burns in the values it found on
the host it was built.

Here's how to get the information:

uname
   returns CYGWIN_NT-4.0 or CYGWIN_NT-5.0 (don't know what it returns on
win95/98
uname -r
    returns 1.1.2s(0.21/2/2) ore simmilar. everything before ( is the version
number; s seems to mean snapshot)
uname -m
    returns i686

or, you could distribute config.guess with your script, it returns
i686-pc-cygwin
a good place to find config.guess is libtool-1.3.5.tar.gz on ftp.gnu.org
