Hi Volodya,

I'm attaching 5 files:
The rsp file (called jnicommon.dll.rsp)

(The last 3 files are for the sake of completeness).

Sorry, I couldn't have my responses at the bottom with my Outlook.

The interesting part is only the first file (aprwrapper.cpp) ends up in the last in the .rsp file (aprwrapper.obj). The order of the rest of the files is maintained.

Thanks again,

Do you give *exact* content of Jamfile and rsp? I am afraid I do not see how such reordering can happen given
the names and types of the files you have provided.

You might want to have


in requirements for the files that need specific order.

I cannot comment without seeing the reproducer.
