It looks as if I'm ready to get rid of NAT_FILE for *BSD/amd64.
Except there's this funny bit of code in configure.in:
if test "${nativefile}" = ""; then
< Makefile \
sed -e '/^NATDEPFILES[[ ]]*=.*\\$/,/[[^\\]]$/s/^/# /' \
-e '/^NATDEPFILES[[ ]]*=/s/^/# /' \
| sed -e '/^\(NATDEPFILES[[ ]]*[[+]]=[[ ]]*\)/s//# \1/' \
> Makefile.tem
mv -f Makefile.tem Makefile
fi
This code comments out the definition of NATDEPFILES if NAT_FILE isn't
there. What's the purpose of this code? Can anybody see a reason why
this code can't be deleted?

As you imply -> it was assuming that nativefile=="" implied no native
support. Grubbing around, there was code like:
if host==target
native=`sed magic ...`
so native= for cross targets was empty and the above would have disabled
native support. The predicate was moved between 5.2 and 5.3 and my
fuzzy memory is because:
- it never really worked
- (possibly) it was realized that "one day soon" GDB would support both
native and true cross debuggers in a single binary

As far as I can tell, ever since 5.3 nativefile!="" has held, and hence
the code was dead.
