This is a problem with the Apple precompiler cpp-precomp.  It does not 
like the GNU technique used in libobjc of compiling a code fragment, using 
it in a couple of compiles and then deleting and recompiling the same code 
fragment for use in the next compile.  I suspect it would be impossible to 
remove this from the Swarm code as long as it is based on GNU objc.  The 
fix is to add -no-cpp-precomp to the CFLAGS thus:

../../../configure \
CC='cc -fgnu-runtime -no-cpp-precomp' \
--prefix=/Users/billn/Public/Swarm/swarm/macosx/swarmx/build/dst/usr \
--with-tcldir=/usr/local/lib \
--without-jdkdir \
--with-hdf5dir=/usr/local

I could commit that configure command to the cvs, because it will soon 
make its way into the PB project.  Do you think that is a good idea? or 
would it be better spooled into the autogen stuff.

Many thanks for your report.  I did the trivial fix of adding a second 
rubbish argument but did not commit it to the cvs because it was obviously 
wrong.  This is my only current uncommitted patch.  If you can see the 
right fix please let me know, and I will commit it.

I currently break here:
cc -fgnu-runtime -no-cpp-precomp -DHAVE_CONFIG_H -I.

I am not quite understanding 'arg 5' there only seem to be four, or does 
it mean the function prototype has five?
