--- Comment #24 from Costas Argyris <costas.argyris at gmail dot com> ---
So this is because of the old (7.3) gcc version not supporting -r.

Indeed, in the 7.3 doc

https://gcc.gnu.org/onlinedocs/gcc-7.3.0/gcc/Link-Options.html#Link-Options

there is no '-r' option while there is in the current doc:

https://gcc.gnu.org/onlinedocs/gcc/Link-Options.html#Link-Options

However, I don't understand how the proposed solution works:

+       $(COMPILER) -r -nostdlib utf8rc-mingw32.o sym-mingw32.o -o $@

since we are still using the -r flag which we just found out doesn't work in
7.3

The fact that -nostdlib somehow makes it work seems like magic to me, and I
can't propose such a patch for that reason.    I also don't know if this fi=
xes
this case of using an old compiler but breaks others.

If Eric feels confident about this and can test that it doesn't break curre=
ntly
working builds, please propose a patch.

Thanks=
