Indeed, after trying a number of different combinations of component versions using the setup application, I found a working set based on gcc/gfortran version 7.4.0. And I get what you mean about Cygwin-specifc adjustments, as one of the codes I tried to compile didn't succeed, and after a google search, found that it was mainly a Cygwin issue. Thankfully, someone was already able to find a fix. The cygwin time machine sounds interesting too, for the case of some really old codes that might need to be dug up and reused. But thank you again for your reply, it has been really helpful.
