Ebcdic should indeed only be enabled by configure, if it finds out
that you are on an ebcdic machine.

There are indeed some features which AFAIK can only be enabled or
disabled by editing feature.h. That's how I'm running with +xterm_save
but -tag_old_static. If you (Robert) really want +tag_any_white you
can uncomment a line somewhere after line 350 of feature.h, but as
Christian implied, the tags files generated by Vim's :helptags
command, or (IIUC) by the Exuberant Ctags program, don't need that
feature.

Beware that if you do this you will have what Mercurial calls two
unnamed parallel changeset chains (unnamed branches?) within the
default branch, which you will have to merge (e.g. by using hg fetch
instead of hg pull -u) every time you get new patches from Bram's
repository. I'm not sure how it works if you use a git clone.

Best regads,
Tony.
