Yes. Here's an example:

cxxosf.zko.hp.com> cat > main.cpp
void foo() {}
int main() {}
cxxosf.zko.hp.com> cat > foo.cpp
void foo() {}
cxxosf.zko.hp.com> cxx -c main.cpp foo.cpp
main.cpp:
foo.cpp:
cxxosf.zko.hp.com> cxx -o main.out main.o foo.o
ld (prelink):
foo.o compressed: foo(void): multiply defined
ld:
foo.o compressed: foo(void): multiply defined
cxxosf.zko.hp.com> cxx -o main.out main.o foo.o -nodemangle
ld (prelink):
foo.o compressed: foo__Xv: multiply defined
ld:
foo.o compressed: foo__Xv: multiply defined
