Thanks for a quick and efficient fix.

MinGW runtime 5.4 looks good: it passes all of my tests (building
hello.c, Emacs, and Gawk), and almost succeeds in building the current
snapshot of GDB, where there's this single problem:

    CXXLD  gdb.exe
  d:/usr/bin/../lib/gcc/mingw32/9.2.0/../../../../mingw32/bin/ld.exe: d:/usr/bin/../lib/gcc/mingw32/9.2.0\libstdc++.a(codecvt_members.o):(.text$_ZNKSt7codecvtIwciE6do_outERiPKwS3_RS3_PcS5_RS5_+0xac): undefined reference to `__msvcrt_wcrtomb'
  d:/usr/bin/../lib/gcc/mingw32/9.2.0/../../../../mingw32/bin/ld.exe: d:/usr/bin/../lib/gcc/mingw32/9.2.0\libstdc++.a(codecvt_members.o):(.text$_ZNKSt7codecvtIwciE6do_outERiPKwS3_RS3_PcS5_RS5_+0x111): undefined reference to `__msvcrt_wcrtomb'

So it looks like the 5.3.x functions are referenced by libstdc++ from
GCC 9.2.0 distribution, and that library (and possibly others which
come with GCC) need to be refreshed as well.

I don't see a new gcc-core-9.2.0-1-mingw32-bin.tar.xz on the MinGW
download site.
