For my mingw build, this fails with:

  CXX      pathstuff.o
../../binutils-gdb/gdbsupport/pathstuff.cc:324:1: error: no previous declaration for 'std::string find_gdb_home_config_file(const char*, _stati64*)' [-Werror=missing-declarations]
  324 | find_gdb_home_config_file (const char *name, struct stat *buf)
      | ^~~~~~~~~~~~~~~~~~~~~~~~~
cc1plus: all warnings being treated as errors

I suppose the definition of "stat" changes between the header and the
.cc file, probably due to the new includes somehow.

I configure like this:

../binutils-gdb/configure '--host=i686-w64-mingw32' '--target=i686-w64-mingw32' '--disable-binutils' '--disable-gas' '--disable-gold' '--disable-gprof' '--disable-ld' '--disable-guile' '--disable-source-highlight' 'host_alias=i686-w64-mingw32' 'target_alias=i686-w64-mingw32' '--without-debuginfod'

This build is done on x86-64 Fedora 32.
