Like #xz, like many free software projects, GNU Fortran is maintained by unpaid and overworked volunteers. It does not stop the US governement ["the original customer"] to ask for gratis work and NOW! https://gcc.gnu.org/bugzilla/show_bug.cgi?id=95644#c6
The customer has nuclear weapons. They do not do "bounty". :) Write that kind of thing in a bug report for a software I maintain, and I can promise whatever you were asking for will never be fixed. Not now, not in 10 days, not in 100 years.
