error setting log-bin-trust-functions-creators=1

[Frehley]

Hi, Im trying to install a mysql service for a noinstall mysql. At the same time I want to set the variable log-bin-trust-functions-creators=1 but it throws this error

100506 10:49:15 [Warning] '--skip-locking' is deprecated and wil be removed in
a future release. Please use '--skip-external-locking' instead.

This is how I install the service

rem comment install.bat
C:
cd C:\MySQL\bin
mysqld.exe --install MySQL-noinstall --defaults-file="c:\MySQL\my.ini" --log-bin-trust-function-creators=1

pause

Any idea of what could be wrong?

Thanks!
