Test for stat/stat64 structs
- To: libc-alpha Mailinglist <libc-alpha at sourceware dot cygnus dot com>
- Subject: Test for stat/stat64 structs

During a discussin with Maciej, he came up with the appended program
which tests that indeed struct stat and struct stat64 are the same
when using _FILE_OFFSET_BITS=64. I've reformatted the file and
patched the Makefile.
What do you think? Should we add this to glibc? It's IMHO a good
sanity check for new architectures.
