Bug report (7): gcc4 on cygwin

gcc4 can't be installed on cygwin due to the file /usr/sbin/fix-libtool-scripts-for-latest-gcc-runtimes.sh not having execution rights - /etc/postinstall/gcc4-core.sh fails with exit code 126. (report)

Update: this bug was already reported by someone else in January and again.
Update 2: it seems to help when the project co-leader steps in. Thanks, Corinna!
Update 20.8.: it works!
