configure option is given on the command line. The value of the arguement is passwd in the enableval variable. The 4th argument tells what to do in case no command line argument was given. This causes --disable-gtk2 (which is the default) to behave differently from the case when no option is given. I do not really understand where the difference in the behaviour of the generated codes comes from, but I definitely see a difference. Fixed all occurrences where the 3rd arguement was empty. svn path=/trunk/; revision=7044
