Summary: occasional build failures with "make -j8"
           Product: Wine
           Version: 1.3.28
          Platform: x86
        OS/Version: Linux

        ReportedBy: [e-mail]

On my i7, where I build with make -j8, I have started seeing occasional strange
build failures.  For instance,

config.status: creating dlls/browseui/Makefile
make[1]: Entering directory
`/home/bob/wineslave.dir/sandbox/slave/runtests-heaptest/build/dlls/browseui'

make[1]: *** No rule to make target `depend'.  Stop.

make: *** Waiting for unfinished jobs....

I've also seen make complain that a Makefile had no separator on line 16XXX,
as if one process was reading it while another was still writing it.

I'll try running "make depend" explicitly as a workaround.
