Hmm at least 9.4 seems to be June 1, 2021 whatever. 11 should be safe? ________________________________ From: Paul Smith <paul@xxxxxxxxxxxxxxxxx> Sent: Wednesday, October 23, 2024 5:40 PM To: Phil Phil <heidegg@xxxxxxxxxxx>; gcc-help@xxxxxxxxxxx <gcc-help@xxxxxxxxxxx> Subject: Re: Gcc 94 / 10.2 has no GCC 20 ?
