~/src/hggcc/gcc/config tobi$ find . | xargs grep ASM_PN
./alpha/vms.h:#define ASM_PN_FORMAT "%s___%lu"
./h8300/h8300.h:#define ASM_PN_FORMAT "%s___%lu"
./ia64/ia64.h:#define ASM_PN_FORMAT (TARGET_GNU_AS ? "%s.%lu" : "%s?%lu")

./v850/v850.h:#define ASM_PN_FORMAT "%s___%lu"
It looks like you do :-)
I wonder why this name-mangling is necessary, it's not like these names
