Name Mangling changed from egcs 1.1.2 to gcc 2.95

Thanks for your bug report. I have problems reproducing that problem,
though. Given

struct snmpGroupProperties;
struct snmpTableGroup{
void _mkGroup(const snmpGroupProperties*, const char*, const char*);
};

void snmpTableGroup::_mkGroup(const snmpGroupProperties*, const char*, const char*){}

both egcs 1.1.2, and gcc 2.95.2 produce

_mkGroup__14snmpTableGroupPC19snmpGroupPropertiesPCcT2

and so does egcs 1.0.2.

I don't know how you've produced the other symbol; whatever compiler
did so, it was a bug in that compiler (perhaps an egcs snapshot??)

No. The linker is not involved with C++ mangling. There is one thing
you can do: write an assembler file (by hand), implementing the
missing symbol by jumping to the existing one.
