1. USEDLL
This appears in configure.in, ./Makefile.am and libobjc/Makefile.am
but I cannot see that it ever gets set. Can I remove USEDLL and
the code which is conditional on it??
It's defined in m4/acdll.m4 by AM_CONDITIONAL.
Also note the reference in libswarm_la_LDFLAGS and for the swarm.dll
rule in src/Makefile.am. The main point of this is/was for Mingw32
(non-Cygwin Windows). Not sure if libtool can do pure Windows DLL
these days.
2. USEBUILTINAVCALL this is only in ./Makefile.am. Again nothing
defines it. Can it be removed??
Similarly in m4/acffi.m4. This is done at the automake level like so:
