Hi Alex and Paolo,
I hit an compiling error with "./configure --enable-rust" at this patch:

I tried to analyze the reasons as follows:
* stubs/monitor-fd.c introduces the same monitor_get_fd() stub as the
stubs/monitor-internal.c did.
* rust-qemu-api-integration used the "link_whole" keyword instead of
"link_with".
Then the two duplicate monitor_get_fd() eventually meet in
rust-qemu-api-integration.
To fix this issue, dropping stubs/monitor-fd.c and only linking
stubs/monitor-internal.c could work! (And I don't think of the reason to
redefine monitor_get_fd() in another file.)
In addition, could we change the "link_whole" to "link_with" when
compile rust-qemu-api-integration?
Thanks,
Zhao
