I'm looking at the objdump -x output for the c++ object and I note that there's
a separate section for the inlined function. It appears to be annotated with a
COMDAT field value of 4. According to skyfree.org/linux/references/coff.pdf a
value of 4 corresponds to IMAGE_COMDAT_SELECT_EXACT_MATCH: "The linker chooses
an arbitrary section among the definitions for this symbol. A multiply defined
symbol error is issued if all definitions don’t match exactly." The C99 symbol
has no COMDAT selection field.
