Patch 8.2.3263
Problem: Vim9: "..=" does not accept same types as the ".." operator.
Solution: Convert value to string like ".." does. (issue #8664)
Files: src/vim9compile.c, src/testdir/test_vim9_assign.vim,
src/testdir/test_vim9_disassemble.vim
After this patch mingw64 (gcc 11.2.0) spits out this warning:

The attached patch tries to fix it.
