I can't seem to find a prior message in the mailing lists about this
problem. A cross build with MACHINE_ARCH=alpha on a FreeBSD/x86 system
fails:
foobar# make MACHINE_ARCH=alpha buildworld
[output elided]
cc -O -pipe -I/home/src-current/lib/libmd -I/home/obj-current/alpha/home/s

Building with -O0 goes further, but not far enough:

The offending line in "libutil/pty.c" has the following code:
char line[] = "/dev/ptyXX";
In fact, the following 1 liner program demonstrates the problem too.
foobar% cat /tmp/a.c
int main() { char line[] = "/dev/ptyXX"; }
And here is the compiler `cc -v' output:

The source tree being built is -current as of yesterday.
Any suggestions on getting a cross world build to work?
