X-Git-Tag: REL6_4_2~771
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=62cd6e7b7559ecd31531df0e5db89d336241e6a5;p=postgresql

Somewhere between 6.1 and 6.3 someone removed the support for the
NS32K machine I contributed.  In any case, I now have postgresql-6.3
running again on NetBSD/pc532, a NS32532 machine.  The following
changes are needed relative to the src directory.  (It looks like
support was partially removed when the files were moved from the
src/backend/storage/.... tree to the src/include tree.)

If you need me to get a current development version of postgresql
for this change let me know.  Also, let me know if this code needs
updating due to another code movement that deleted the old NS32K
support.

Thank you.

Phil Nelson
