[31724s] ../../../../libgfortran/io/unix.c: In function ‘find_file’:
[31724s] ../../../../libgfortran/io/unix.c:1704:26: error: ‘id’ undeclared
(first use in this function)
[31724s] 1704 | # define FIND_FILE0_ARGS id, path

[31724s] ../../../../libgfortran/io/unix.c:1778:30: note: in expansion of macro

[31724s] make[6]: *** [Makefile:6863: unix.lo] Error 1
which is because find_file does
#if defined(__MINGW32__) && !HAVE_WORKING_STAT
id = id_from_path (path);
#endif
RDLOCK (&unit_rwlock);
retry:
u = find_file0 (unit_root, FIND_FILE0_ARGS);
so as long as __MINGW32__ is not defined this won't work. The fix might
be to remove the __MINGW32__ part of the conditional.
(and no, I didn't yet know how we arrived at !HAVE_WORKING_STAT - this is on
x86_64 linux, but with a -j1 build - see
