Subject: The hack for /dev/fd support on systems without it was removed a
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=855754a1910d1c0da9400c184f1e3f4f6bb1242a;p=openbsd

The hack for /dev/fd support on systems without it was removed a
long time ago.  Update the comments and replace test_stat() calls
with stat() since test_stat() now just calls stat() directly.  Also
rename the "mode" parameter to "amode" in test_eaccess() to match
access(2) and make it clear that this is the access mode and not
the file mode.  OK jca@
