| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Daniel Richard G. for the patch; kept the autoconf requirement to 2.60 instead of changing it to 2.68 as done with autoupdate, since 2.60 seems to be sufficient according to the changes and 2.68 is too recent, e.g. Debian/stable still has 2.67). --- Note --- This update has another effect: The "Configs for Windows DLLs." code (from "case $host in" to "esac") is now executed at the right time, after options like --disable-static are taken into account. Juste before this change, the test if test "$enable_shared" = yes; then was always false.
