Subject: Accept alternate spellings of __sparcv7 and __sparcv8.
X-Git-Tag: REL9_6_BETA1~1509
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=1f64ec6fd28bcd2be9b6b0ad3a5a630e117db601;p=postgresql

Accept alternate spellings of __sparcv7 and __sparcv8.

Apparently some versions of gcc prefer __sparc_v7__ and __sparc_v8__.
Per report from Waldemar Brodkorb.
