Hi:

AMD64 X2 system and the build error is

"""
/usr/src/sys/platform/pc32/i386/genassym.c:1: error: -mpreferred-stack-boundary=2 is not between 4 and 12
"""

Why exactly does the -mpreferred-stack-boundary=2 need to be between 4 and 12 ?

Here is some process information, if this helps,

hw.machine: amd64
hw.model: AMD Athlon(tm) 64 X2 Dual Core Processor 4400+
hw.ncpu: 1
hw.machine_arch: amd64
