[BUILD] Fixed build on OS X
Hi, Herbert and friends. I've created a small patch that allows dash to be built on Mac OS X. I'm contributing it here with the hope that it's suitable for inclusion in dash. The changes in this patch are: - __attribute__((__alias__())) is not supported, add an autoconf check - open64 is not present although the stat64 family is, separate the autoconf checks - A syntax error had slipped into a non-glibc codepath - mkbuiltins had a nonportable mktemp invocation for the case where tempfile is not availalble Nothing in this patch is actually Mac OS X-specific, so it might aid portability to other platforms as well.
