The C Standard doesn't disallow it, though it does say that the behavior
of "" and <> are both implementation-defined.

OK, thanks, then we might as well try using "" everywhere. I'm more
comfortable with "///..." anyway; the <///...> gave me the willies,
since a compiler might think it was a C99 comment.
If "" doesn't work someplace else, then we'll need another
compile-time test.
I installed this into gnulib and coreutils:

* absolute-header.m4 (gl_ABSOLUTE_HEADER): Use "" rather than <>
around the absolute name, to work around a problem with the HP-UX
11.23 native C compiler, reported by Bob Proulx.
