Unable to build acpi_asus module on current today

Today I tried rebuilding my laptop running current. Building the kernel
module acpi_asus, the build bombed with the error:
===> acpi_asus (all)
cc -O2 -fno-strict-aliasing -pipe -Werror -D_KERNEL -DKLD_MODULE -nostdinc -I-

/usr/src/sys/modules/acpi/acpi_asus/../../../dev/acpi_support/acpi_asus.c:584: error: 'for' loop initial declaration used outside C99 mode

But this module has not been touched since April and I have built all of
it many times since then. Several other modules seem to have the same
problem of declaring a variable in a for statement.

I moved the declaration to its own statement before the "for" and it
compiles fine.

Did some compiler default recently change? I have no compile options on my
make.conf.
