I'd guess because bcopy is deprecated that someone wrote up a macro like
#define bcopy(x, y, z) memcpy(y, x, z)
Use "gcc -E -dD <source-file>" and have a look at the output to find out if
that is the case and where it gets defined. Just remove it or make sure that
it gets #undef'd before including <strings.h>.
