I'm trying to hide symbols in dso.o, but -hidden and -non_hidden are separated from
dso.o...
# cxx -shared -o dso.so -Wl,-hidden dso.o -Wl,-non_hidden -v
generates...
# /usr/lib/cmplrs/cc/ld -o dso.so -hidden -non_hidden -g0 -O1 -shared
/usr/lib/cmplrs/cxx/_main.o dso.o -lcxxstd -lcxx -lexc -lc
Is there any way to keep them together?

| Try this: -Wl,-hidden,dso.o
Please see the C++ man page for more information about how to pass switches
using -W.

Unfortunately cxx then thinks it has no objects to process so returns
immediately. I've checked -Wl on the man page but that doesn't help.

NB: I first tried feeding /dev/null to cxx, but the linker was unhappy - it
wanted a COFF format file. That's why I compiled the empty file to generate
a COFF file with nothing interesting in it.
