FW: Use of DLLIMPORT with common blocks

[Rotach, William F]

Greetings Fortran team:
       I am working on a Fortran project that utilizes common blocks across multiple shared objects, written in C and Fortran.  We are currently using a copy of gcc 4.8.1, and have tested version 4.4.7 as well, where I have a similar response to bug # 47030.
       I have found that any use of the "!GCC$ ATTRIBUTE DLLIMPORT :: <variable>" generates one of the following: 
"warning: 'dllimport' attribute directive ignored"            - when applied to a variable name
"Error: Invalid character in name at (1)"                                - when applied to a common block "/ variable /"

                I assume the second is in response to the use of the slash, "/", and not the variable name itself.

                In the end, what I need is for multiple Fortran modules to access variables in a dynamic library, that is also accessed by dynamically linked "C" libraries.
                Any suggestions to lead me to this end result would be appreciated.

                Regards,
                Will Rotach
