Bcp Errors With Queryout

I am having problems running bcp with queryout. I believe some of this stems from the fact that I also have the Sybase tools installed on the database servers and it in turn added its binn directory for the Sybase bcp.exe to the environment variables. Seeing this then, I would like to resolve this issue with a solution that does not rely on the order of environment variables.

Here is what is happening:

1) If I just try to run bcp on my server I get...

exec master.dbo.xp_cmdshell 'bcp ?'
/*
output --------------------------------------------------------------
'bcp' is not recognized as an internal or external command,
operable program or batch file.
NULL
*/

2) ...so, I add the full path to the location of the bcp program and this command works:

exec master.dbo.xp_cmdshell '"C:Program FilesMicrosoft SQL Server80ToolsBinncp.exe" ?'
/*
output ------------------------------------------------------------------------------------usage: C:Program FilesMicrosoft SQL Server80ToolsBinncp.exe {dbtable | query} {in | out | queryout | format} datafile
[-m maxerrors] [-f formatfile] [-e errfile]
[-F firstrow] [-L lastrow] [-b batchsize]
[-n native type] [-c character type] [-w wide character type]
[-N keep non-text native] [-V file format version] [-q quoted identifier]
[-C code page specifier] [-t field terminator] [-r row terminator]
[-i inputfile] [-o outfile] [-a packetsize]
[-S server name] [-U username] [-P password]
[-T trusted connection] [-v version] [-R regional enable]
[-k keep null values] [-E keep identity values]
[-h "load hints"]
NULL
*/

3) I then attempt a bcp out of a Northwin table... and this works as well

DECLARE @cmdline VARCHAR(4000)
SELECT @cmdline = '"C:Program FilesMicrosoft SQL Server80ToolsBinncp.exe" Northwind.dbo.Categories out C: est.txt -c -T'
EXEC master..xp_cmdshell @cmdline--, NO_OUTPUT
/*
output
-----------------
NULL
Starting copy...
NULL
8 rows copied.
Network packet size (bytes): 4096
Clock Time (ms.): total 31
NULL
*/

4) I then attempt a queryout and it fails, indicating that it no longer understand the long filename

DECLARE @cmdline VARCHAR(4000)
SELECT @cmdline = '"C:Program FilesMicrosoft SQL Server80ToolsBinncp.exe" "SELECT CategoryID FROM Northwind.dbo.Categories" queryout C: est.txt -c -T'
EXEC master..xp_cmdshell @cmdline--, NO_OUTPUT
/*
output ------------------------------------------------------------------
'C:Program' is not recognized as an internal or external command,
operable program or batch file.
NULL
*/
