MCC: m-code to dll

Hello all,

We are developing functionality (m-code) that will be used by our
contracters. Several files were packed into single dll function ready
to be used by our contracters.
Advantages:
* Code is hidden
* only one function needs to be transferred, instead of multiple
m-files.

Since the "mcc -x" option doesn't work anymore, only valid option is
to used p-code, but then I will have several p-code files.

Is there another option that I'm not considering ???

Thanks in advance,
Frederik
