I think that the current consensus is that everyone is tired about
excuses like "no inclination" or "no time" or "vacation" or "death in
the family" or "newborn baby". Frankly, I think if there is an issue
you should be fixing it. This issue has clearly been in the code for a
long time and, although it probably doesn't work on MSYS2, that should
be no excuse for not fixing it in Cygwin.
