Ideally you should use M4, if you have it. M4 was designed for just this
sort of task:
m4 -D'bcopy=memcpy($2,$1,$3)' \
-D'bzero=memset($1,0,$2)' \
-D'bcmp=memcmp($1,$2,$3)' file.bsd > file.posix
except that you can't blindly replace bcopy() with memcpy(). nor does
this handle m4 reserved words very well.
but if you solve those problems, m4 is probably the `best' solution,
as it becomes a painful experience to try to match parens correctly
in other languages (such as perl).
that said, i still prefer the solution i posted at the start of this
thread.
