+Subject: [PATCH] libgo: use POSIX shell arithmetic expansion
+MIME-Version: 1.0
+Content-Type: text/plain; charset=utf8
+Content-Transfer-Encoding: 8bit
+
+Avoid bash-specific ((expression)) syntax.  As the bash syntax
+converts a non-zero value to a zero status (and a zero value to a 1
+status), and POSIX arithmetic expansion does not, we have to negate
+the result.
+
+Based on patch by Sören Tempel.
