libfplll does not build on cygwin #22807

@embray, I am willing to test all the nice patches you have produced for Cygwin. But first I have to get there, which I am unable to do because of this |

By the way, there are also a bug with building ECL on Cygwin 2.8.0 (the latest version). I haven't made a ticket for that yet but basically we need to add |

Also, as a minor status update, a lot of stuff was broken in my most recent build of develop (plus my additional patches). I mean it built, but a lot of tests were broken. Which is disheartening because last week I had it down to one test failing and now in just the space of a week the test suite is barely passing at all. One thing I'm worried about is that on Monday I upgraded my Cygwin install and that could have caused all sorts of issues. I don't know what package versions I was at before the upgrade though so it might be difficult to reproduce. I'm trying a build now on a slightly older Cygwin install that I already knew to work for sage 7.4.... |

tospkg-install
. Then the above file compiles correctly, but the final stage of the compilation (to producelibfplll.dll.a
) hangs forever.CC: @embray @tscrim
