odd libmspub build issue ...

        I just got the attached; building master on windows, with 10x way
parallelism (only 8 cores but ...).

        Unclear to me what is/was going on - the Makefile.am rule looks fine:

libmspub_@MSPUB_MAJOR_VERSION@_@MSPUB_MINOR_VERSION@_la_SOURCES = \
        MSPUBCollector.cpp \
        MSPUBDocument.cpp \

        Also looks like that object was compiled first, so - surely it's
completed by the time linking starts ? I've got ccache disabled so no
possible race there.

        Only happened the 1st time on a from-clean initial git checkout of
master - rather odd; I wondered if anyone else has seen that ?

        HTH,

                Michael.
