Substituting local modules with the same name as the GM2 modules

[john o goyo]

Greetings, Gaius.

I am trying to build some old code that uses a different version of 
Storage.  I have a local version to reflect this and I am using the "-I" 
directive.  The compiler picks up my local version for compiling local 
modules but it also uses my local version for gm2 modules.

In particular, examining m2/m2pim/Indexing.def pulled in my local 
Storage.def and failed.

Hence my query:  Is it even possible to instruct the compiler to use 
local modules for local compilation only (or must I rename them)?

Sincerely,
john
