The 'e' modifier to fopen() has the effect of adding an O_CLOEXEC to the underlying open() call.
BY preprocessing 'fopen.c', I see the 'rpl_fopen()' in my case is rather short. Since 'GNULIB_FOPEN_GNU' seems *not* to be defined, it passes mode to 'orig_fopen()' with "re" intact. Hence the EINVAL. I've no idea who/how '-DGNULIB_FOPEN_GNU' is supposed to be set. But manually adding it, all is well.
It should be supported in GNU diff, because the 'exclude' module depends on the 'fopen-gnu' module, and this module implemented the 'e' modifier. What is the value of file_name here?
'exclude'. -- --gv
