Cool.  FreeBSD/i386 seems operational as built from FSF tree after
your update.

Thanks for the "heads up".  Agreed, we indeed rolled that patch into
Boehm's copy from our tree.  It now appears about 10 lines above with
a (hopefully, gratuitous) setting for NEED_FIND_LIMIT (I shant touch
it since I don't know why it was added but it seems mostly harmless).

Now `ccvs diff -rGC_6_3_ALPHA_1 -w os_dep.c' reports no difference.
Committed as obvious (after rebuild and test in already built tree).

	* os_dep.c: Remove redundancy introduced in last merge.
