The radr://6320843, "duplicate symbols from static libraries not properly
ignored", has been open since 26-Oct-2008. I later opened radr://6733684,
"duplicate symbols in static libs not properly ignored when linking in 10A###"
with additional examples including...

gcc -I/sw/include -DXNO_MTSAFE_STRINGAPI -DXNO_MTSAFE_PWDAPI
-DXNO_MTSAFE_TIMEAPI -Wall -g -fno-strict-aliasing -Wno-unused -Wno-comment

ld: duplicate symbol _main in
/sw/src/fink.build/openmotif4-2.3.1-3/openmotif-2.3.1/tools/wml/libwml.a(wml.o)
and wml.o

from openmotif 2.3.0 and it was closed as a duplicate without additional
comment. I don't think Apple views this as a critical bug but rather coddling
lazy programmers.
