K 10 svn:author V 4 fjoe K 8 svn:date V 27 2010-02-10T04:08:18.000000Z K 7 svn:log V 348 Due to mistake in virtuoso startup scripts the following error can happen during the build: expr: illegal option -- N usage: expr [-e] expression where N is any decimal number, because some variables used in "expr" invocations can be negative integers. Protect against this error (although the workaround does not fix the root of this problem). END
