collect2: ld returned 1 exit status

there are no warnings compiling spvw.c
is there a way to figure out what is going on?

If the problem comes from spvw, you can hunt it by doing "make spvw.s"
and looking for errno references there.

But the problem can also be related to other libraries, and possibly
the use of incompatible ABIs (the famous -ML, -MT, -MD flags).
