I'll just add at this point that when I went back over the thread (looking for that cygcheck.out), I found your test case and
can't exactly reproduce your results:
dk@rainbow /test/exec> gcc test2.c -o test2
dk@rainbow /test/exec> PATH=/usr/bin:.
dk@rainbow /test/exec> test2 nopathnoext
NoPath
dk@rainbow /test/exec> touch echo
dk@rainbow /test/exec> ls -l echo
-rw-r--r-- 1 dk Domain Users 0 Jan 31 18:32 echo
dk@rainbow /test/exec> test2 nopathnoext
NoPath
dk@rainbow /test/exec> PATH=.:/usr/bin
dk@rainbow /test/exec> test2 nopathnoext
nopathnoext: Permission denied
dk@rainbow /test/exec> rm -f echo
dk@rainbow /test/exec> test2 nopathnoext
NoPath
dk@rainbow /test/exec> echo garbage > echo
dk@rainbow /test/exec> test2 nopathnoext
nopathnoext: Permission denied
dk@rainbow /test/exec> ls -l echo
-rw-r--r-- 1 dk Domain Users 8 Jan 31 18:33 echo
dk@rainbow /test/exec> test2 nopathext
NoPathExt
dk@rainbow /test/exec> test2 path
Usage: test2 nopathnoext|nopathext|pathnoext|pathext
dk@rainbow /test/exec>
This is at least partly down to the fact that you either a) forged your results rather than cutting and pasting them or b)
attached a different program from the one you actually used as a testcase when you sent your email!
cheers,
