Hi,

while building Cygwin hosted toolchain build was mysteriously failing with
'No such file or directory'. Here's a test case:

P=/tmp
for i in 1 2 3 4 5 6 7 8
do
  P=$P/this_is_somewhat_very_long_path
done
mkdir -p $P
(cd $P && pwd)

pwd outputs just '.', but once editing loop to end at 7th iteration (thus
making path shorter than 255 characters) it prints path correctly.

The problem is that 'cd' cannot change directory to path longer that 255
characters and fails silently with exit status 0. Is it known/expected
behaviour?

Cygwin DLL version 1.7.7 on Windows 2003 Server Ver 5.2 Build 3790 Service
Pack 2, running under WOW64 on AMD64.

Thank you,
	ladis
