> 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.
