Rewrite FortranCInterface module This is a new FortranCInterface.cmake module to replace the previous prototype. All module support files lie in a FortranCInterface directory next to it. This module uses a new approach to detect Fortran symbol mangling. We build a single test project which defines symbols in a Fortran library (one per object-file) and calls them from a Fortran executable. The executable links to a C library which defines symbols encoding all known manglings (one per object-file). The C library falls back to the Fortran library for symbols it cannot provide. Therefore the executable will always link, but prefers the C-implemented symbols when they match. These symbols store string literals of the form INFO:symbol[<name>] so we can parse them out of the executable. This module also provides a simpler interface. It always detects the mangling as soon as it is included. A single macro is provided to generate mangling macros and optionally pre-mangled symbols. 2009-08-05 21:40:29 +04:00			`module my_module`
