Ah, that helped, thanks. This dependency is missing from gcc-4 though.

Yes, sure, I didn't try to install both at the same time. I wanted to
install some version which is working. Gcc-4 didn't run due to error
above, and I didn't find a way to install gcc-5 without GUI.

I thought that it's related to gcc-5 because of
https://cygwin.com/ml/cygwin/2015-09/msg00282.html
And before upload of gcc-5 to the archive, gcc-4 was working fine when
installed this way (just gcc-g++, without explicit libisl10)

This would enable me to install gcc-5, which is another way to
workaround problem of a non-working gcc-4. Such features would be useful
in other situations too.
