The Configure script seems not to recognize the UNIX commands defined in CygWin (cmd, tr, mkdir, cd, chmod, rm, cat, sed, awk, touch, ...), therefore an automatic installation with Configure cannot be initiated on Windows/CygWin systems. The version of CygWin I used is "1.3.9(0.51/3/2) 2002-01-21", I didn't verify if it applies also to the old version B20.1 suggested in the Installation Guide. It would be useful if the automatic procedure for installation can be applied to Windows systems as well.
BTW, in Bugzilla when opening a new problem report, if I explicitely choose the person to assign the ticket, it does not work and Bugzilla still assigns the ticket to the default defined in the Bugzilla database ......
Since the last release of G4 4.1 Configure works in Cygwin env.
