Hmm.  Yes, that option *is* available in Mandrake's gcc-2.96, and
it does fix the problem there too :)

The manpage I have *does* note C99 conformance, but that isn't
sufficient, IMO -- it should also have a `Caveats and Bugs' section,
in which it *explicitly* specifies the requirement to compile with
the `-std=c99' option, (or some other standard conformant option).
In this respect, this is a bad manpage.

The *implementation* is also bad, for without an appropriate `-std'
option, the application will still compile and link without a murmur,
only to fail miserably, and *incomrehensibly*, at run time.

But this isn't the right place to complain of this.  Is it a GCC
issue?  Or should it be reported somewhere else?  I simply don't know
where to go with the bug report :(  (And that's another omission from
the manpage).

Keith.
