Hello, I didn't take a try with other mingw gcc version, locally I just revert
304c7d44a2212e6fd618587331cea2c266dc10bf commit, then it works for me.
Thanks

What is the version of the cross-compiler, cross-binutils and make that you are
using to build gcc for windows from linux?

For some reason you are compiling gcc/utf8-mingw32.o as an executable, which
shouldn't be happening.
This is the rule for it in gcc\gcc\config\i386\x-mingw32-utf8
utf8-mingw32.o : utf8rc-mingw32.o sym-mi

It's the -r option passed to the compiler, it was not really supported in older
compiler (and certainly not documented).

Can you add -nostdlib alongside -r in the command?

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

I am not aware of any cases of building windows-hosted gcc with msvc or clang.
If the combination -r -nostdlib fixes this case without breaking all the others
that don't need -nostdlib (which sounds like

Hi Huaqi,
Patch has been pushed to master, you should now be able to get the latest gcc
sources and build without having to apply it manually.

OK, thanks

Regarding usage of the -r flag:
Building windows(mingw)-hosted gcc with clang at this point seems highly
experimental at best, and impossible with msvc.
With clang (lld linker), -r is supported with ELF,
