With the new program, with MOVB defined, completes successfully, with MOVB
undefined, completes successfully. Both works. Hmm! Using gcc 2.95.2,
glibc 2.1.3 w/linuxthreads.

Here's my /proc/cpuinfo

processor : 0
vendor_id : GenuineIntel
cpu family : 6
model : 1
model name : Pentium Pro
stepping : 7
cpu MHz : 166.194480
cache size : 512 KB
fdiv_bug : no
hlt_bug : no
sep_bug : no
f00f_bug : no
coma_bug : no
fpu : yes
fpu_exception : yes
cpuid level : 2
wp : yes
flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov
bogomips : 165.89
