This is a standard autoconf test from sanity.m4; it's not
mysql-specific.  If it was buggy, I think a lot more than one person
would be complaining :)  FreeBSD uses ash as /bin/sh and I've never
seen this error.

Take a look at configure.log and see if there are any error messages
in there that might point you to the exact problem.
