This would seem to be problematic, as different source files could have 
been compiled with different switches. Some features aren't necessarily 
isolated to single source files.  For example, as someone else 
mentioned, recursive I/O often (and even typically) involves two 
different procedures. Neither procedure alone makes the I/O recursive; 
the recursion only happens when you use the two together.

I've seen some run-time things that end up being controlled by the 
switch settings used for the main program. Though that can still raise 
"issues" (such as what happens if the main program is not in Fortran). 
It is also likely "distant" from the code that depends on the settings.
