With the exception of a slight bit of file name conversion, I get the same
result as you do with Cygwin when I run on Linux (FC4):
# /tmp/a
/dev/fd/63
OK
# /tmp/b
lr-x------ 1 lhall lhall 64 May 29 23:26 /dev/fd/63 -> pipe:[916212]
cat: /dev/fd/63: No such file or directory
This is using your scripts verbatim.
