Re: MacOS X last lap

I can't see that the avcall library has anything to do with it. avcall.lo, 
structcpy.lo and .libs/libavcall.al all contain the symbols only once. The 
problem is clearly the link  command which lists the library twice.

rm -fr .libs/libdefobj.la .libs/libdefobj.* .libs/libdefobj.*

../../avcall/.libs/libavcall.al(avcall.lo) definition of ___builtin_avcall 
in section (__TEXT,__text)

I suspect the gnu linker ignored the duplication, which has hidden the 
error previously, but it seems dyld on the Mac does not.    If I delete 
the duplication in the command it links.   Unfortunately even though  can 
build the library by hand, running make again insists on buildng it agan 
and fouling up.  I am trying to hack the makefile which generated the 
command, but it is rather complicated.
