Currently, the "export" modifier apparently does not add an alias for the unmangled name, so I'm not sure how you are even getting things linked successfully.

You posted the source to a library. It is not possible to run a library. So again: what is the program that you wrote that imports that routine and how did you import that routine in that program?

Additionally, afaik FPC does not currently support creating statically linkable libraries. So how did you statically link a compilation unit that starts with the "library" keyword into a program?

What is the error that you got?

a) it makes the routine's symbol public, so that it can be referenced from other object files
b) for the OS/2 and EMX targets, it also adds the routine to the "deffile" (I don't know the details about that)
