bootstrap from 5.16->5.19

[Russell L. Carter]

Hi,
Is there a workaround for getting from 5.16 to 5.19 svn?  5.16
ragel won't compile 5.19's rl files.  Debian sadly is still
back in 5.16 for the unstable package, and the 5.19 rpm's complain
about needing GLIBC_2.4 when I install them on either my
RHEL4, or 32bit debian boxen.

I am motivated to try to do this to avoid having to pass through
all those syntax changes I see in the changelog...

Thanks,
Russell
