Thanks!  This patch is ok modulo three formatting remarks I'll make below.  I
see that you still don't have write access, and Steve remarked that the patch
doesn't apply  to his tree, so can you please send an updated diff, which I
will then happily apply if it gets here before Monday morning, where I'll
leave town for a week.

Two blanks please.  I don't know why.

Should be:
 	PR fortran/22390
 	* dump-parse-tree.c (gfc_show_code_node): Add case for FLUSH.
 	* gfortran.h: Add enums for FLUSH.
 	* io.c (gfc_free_filepos): Modify comment appropriately.
	(match_file_element, match_filepos): Likewise.
        (gfc_match_flush): New function.
etc.

Please no empty line in the beginning of the function.
