That would work for HP-UX 11, where <limits.h> defines PASS_MAX to be 8.  I
don't have access to older HP-UX boxes, which presumably have the
8-character limit but might have less useful <limits.h>.   The HP-UX 11 man
page for cpp claims that "all HP-UX systems have the symbols PWB, hpux,
unix, _PWB, __hpux,  and __unix defined", if you want other symbols to test
for.
