--- Comment #10 from Jerry DeLisle <jvdelisle at gcc dot gnu.org> --- Created attachment 32217 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=32217&action=edit Substantial patch This patch is larger then it looks due to my editor judiciously removing trailing space in write.c. The patch passes regression testing. I modified the way we handle disabling delimiters for writing the namelist narrative. I also made use of the DELIM_UNSPECIFIED to indicate defaulting to "quote". I will post to list for approval on my next opportunity.
