kernel compile error, 5.2.1-RELEASE

Hi,

Just trying to get a kernel built on a 5.2.1-RELEASE box.  Am encountering
this error:

cc -c -O -pipe -march=pentiumpro -Wall -Wredundant-decls -Wnested-externs -Wstrict-prototypes  -Wmissing-prototypes -Wpointer-arith -Winline -Wcast-qual  -fformat-extensions -std=c99  -nostdinc -I-  -I. -I/usr/src/sys -I/usr/src/sys/contrib/dev/acpica -I/usr/src/sys/contrib/ipfilter -I/usr/src/sys/contrib/dev/ath -I/usr/src/sys/contrib/dev/ath/freebsd -I/usr/src/sys/contrib/ngatm -D_KERNEL -include opt_global.h -fno-common -finline-limit=15000 -fno-strict-aliasing  -mno-align-long-strings -mpreferred-stack-boundary=2 -ffreestanding -Werror  /usr/src/sys/dev/fb/vga.c

I've experienced and worked around this manually before on other 5.x systems,
but never reported it hoping someone else would notice it and make the
effort. :)  Can't seem to find anything in the archives either.  Is this a
bug or something I'm doing wrong?


Thanks,
