>Environment:
System: NetBSD 2.0C
Architecture: i386
Machine: i386
>Description:
/proc/cpuinfo provided for -o linux option by procfs uses different
capitalization of two cpu-related fields than Linux which could result
in wrong behaviour of some applications.  namely configure script of mplayer,
which guessed wrong cpu family for my machine (default "pentium4" instead of
correct "pentium3").
>How-To-Repeat:
try to compile mplayer (i'll fix the package not to rely on /proc/cpuinfo on
other systems than Linux, though) with /proc mounted with -o linux (in my case
a symlink to /usr/pkg/emul/linux/proc).
