Please show a sample program that demonstrates this problem and the full command line that you used to compile it (and copy/paste the options that you used to compile the compiler/rtl).

Is this still about moving the function to another unit solving the problem you had, or an unrelated remark?

Comp is an x87-specific legacy type. On platforms without x87 support it is emulated using int64 (so there it is an integer type rather than a floating point type). You should not use the comp type if you want portable code.

I don't understand what this has to do with what I said above, or with your ldfd-problem though. Please do not reply to some sentences in a previous mail if you want to explain something else, it makes the discussion confusing. Either write a separate mail, or delete the unrelated sentences.
