BUILD FAILURES ON CURRENT SOURCES AFTER GCC12 UPDATE

[Brian Buhrow <buhrow%nfbcal.org@localhost>]

	hello.  I'm trying to build release using -current sources on an older -current system
NetBSD-9.99.77 and I'm getting the following error with any sources after the gcc12 import.
Is this expected behavior and, if it is, what is the work around?
-thanks
-Brian


I'm building with command:

./build.sh -D /var/tmp/netbsd-current-64 -O /usr/local/netbsd/obj-current-64 -j 4 release


The errors are:
