Hi, ever since everybody's shouting "We're open!", mainframes have learned a few Unix manners, which is a good thing. Alas, while being quite close to Posix, they'll use Ebcdic rather than Ascii, which causes no end of headaches.
Since autoconf seems to have no test for this, I've figured one out, which you might want to provide: [ "`echo A`" = "`echo '\0301'`" ] the corresponding Ascii test would check for \0101 instead. While piping the output of echo back into the test operator seems rather cludgy, I know of no simpler way. And at least this should be portable across all Bourne shells. enjoy Daniel -- Kommunikation ist unwahrscheinlich. / Komunikado estas neprobable. Niklas Luhmann, Soziologe / Sociikisto
