Very weird: on OpenBSD the strings of length 1 work and the larger ones
fail, and on Cygwin 1.5 it's just the opposite!

Thanks. Still, I prefer to separate the two tests: It takes more time
to understand a test if it's clobbering the input data of the previous
test.
Also, in the doc I prefer to keep a canonical order of platforms. This makes
it easier to compare lists of platforms. The complete list, which you see
for example in doc/posix-functions/posix_trace_attr_init.texi, can be
memorized as follows:
1) the widely used Unices: glibc 2.3.6, MacOS X 10.3,
2) the other free Unices: FreeBSD 6.0, NetBSD 3.0, OpenBSD 3.8,
3) the proprietary Unices, sorted alphabetically:
AIX 5.1, HP-UX 11, IRIX 6.5, OSF/1 5.1, Solaris 10,
4) the Windows based systems: Cygwin, mingw, Interix 3.5,
5) rarely used and hobbyist systems: BeOS, Haiku, etc.
This ordering is quite arbitrary, but sticking to it should help anyway.
Hope you don't mind.
