echo $PATH gives (line breaks by me):

PATH=/usr/local/bin:/usr/bin:/bin:/c/bin:/c/usr/bin:/c/usr/local/bin:\
/c/WINNT/system32:/c/WINNT:/c/WINNT/system32/wbem:/c/sfu/telnet/:\

/c/apps/jdk1.2.2/bin:/c/spi/bin:/c/Program Files/GNU/WinCvs:\
/c/Program Files/Microsoft Visual Studio/VC98/Bin

ls "c:\\Program Files\\Diskaccess\\bin" gives:
daconfig.exe*
nfs.exe*

try to execute daconfig/daconfig.exe or "type" them give:
bash: daconfig.exe: command not found
bash: daconfig: command not found


cygcheck (note corrupted [split] quotes across a path element and inclusion
of quote chars in the path elements) gives:

If I remove the quotes from the system environment variable
in the control panel and reboot, all works:

echo $PATH gives (line breaks by me):

PATH=/usr/local/bin:/usr/bin:/bin:/c/bin:/c/usr/bin:/c/usr/local/bin:\
/c/WINNT/system32:/c/WINNT:/c/WINNT/system32/wbem:/c/sfu/telnet/:\

/c/apps/jdk1.2.2/bin:/c/spi/bin:/c/Program Files/GNU/WinCvs:\
/c/Program Files/Microsoft Visual Studio/VC98/Bin

type daconfig gives:

daconfig is hashed (/c/Program Files/Diskaccess/bin/daconfig)

and the path section of cygcheck is

Path:	/usr/local/bin
	/usr/bin
	/bin
	/c/bin
	/c/usr/bin
	/c/usr/local/bin
	/c/WINNT/system32
	/c/WINNT
	/c/WINNT/system32/wbem

	/c/apps/jdk1.2.2/bin
	/c/spi/bin
	/c/Program Files/GNU/WinCvs
	/c/Program Files/Microsoft Visual Studio/VC98/Bin

Which is all correct.

Therefore, I think there is an incorrect interpretation (or conversion)
of quoted windows paths.  For one thing, it appears to be using the colon
in "c:b" as a path separator instead of grouping it all together according
to the higher precidence quotes.

PS.  I looked in the FAQ, thru the mailing lists (search words +quote +path
and +quoted +PATH, and didn't see anything).

PPS.  I wrote a version of the "which" command, in which I did some really
minimal parsing of quoted windows paths, but it works correctly in the
cases above.  I noticed this same problem in my program a while ago, (and
fixed it by adding the minimal quote parsing).  Didn't think to check
cygwin's operation.

I can forward my "which" program to anyone who wants it.
