Hello,I found AC_FC_MODULE_OUTPUT_FLAG does not know the -mdir option to nagfor and added that. And while I was at it, I also did some change to make the shell code a little safer. Can you include the patch as is or is it missing something?
Regards, Thomas

Subject: [PATCH] Add module output directory flag for NAG compiler.
* Also use autoconf macros instead of verbatim shell code and make tests
safer.
