Missing stdarg.h breaks build
-----------------------------

                 Key: LUCY-175
                 URL: https://issues.apache.org/jira/browse/LUCY-175
             Project: Lucy
          Issue Type: Bug
    Affects Versions: 0.2.1 (incubating), 0.2.0 (incubating)
            Reporter: Marvin Humphrey
            Assignee: Marvin Humphrey
             Fix For: 0.2.2 (incubating), 0.3.0 (incubating)


The autogenerated header file "autogen/Lucy/Test.h", derived from
core/Lucy/Test.cfh, incorporates va_list arguments and therefore requires
stdarg.h.  The fact that stdarg.h is missing causes autogen/parcel.c to fail
to build on some systems.

The solution is to pound-include stdarg.h within charmony.h, which gets
pound-included before any autogenerated header content.  Alternately, we could
pound-include stdarg.h within Test.cfh alone (as was done within CharBuf.cfh)
but since Clownfish *always* allows va_list as a variable type specifier, the
more robust fix is to ensure that stdarg.h is always pound-included where it
might be needed.

This problem does not afflict 0.1.x because by coincidence, Test.h was always
pound-included after another header file which pulled in stdarg.h.
