Lx51 "Data Type Different" Warnings ?

Hello.

I have a project that links to a library I created using the C51 toolset.

If I build it using BL51, everything's cool. If I build it with Lx51, I get warnings like this:

*** WARNING L25: DATA TYPES DIFFERENT
    SYMBOL:  _FnName
    MODULE:  .\main.obj (MAIN)

though the application appears to work just fine in the simulator.

If I build the project with source files only (i.e. I compile the modules that are normally in the library, and I don't link to the library) then everything works under BL51 and Lx51.

So, what can I do to enable me to build projects using Lx51 and my libraries, and avoid these "Data Type Different" Warnings?

Does this compiler do array bounds checking?
I s'pose that might be a reason for it to want the size

If my compiler did array bounds checking, I would shoot it!

I use negative array indexing all the time for useful kinds of stuff.

Andrew asked "Does this compiler do array bounds checking?"

Probably. Our arrays in question are arrays of struct, and all access is through pointers.

Does the ANSI C standard say anything about this issue (how to declare extern arrays)?
