Some additional remarks:
- Before you use it for production, I'd remove -fcheck=bound as it slows
down the code. (The option is helpful to find bugs in the code,
especially when implementing new features. But if the code is debugged,
it can be removed.)
- You do not have any optimizations enabled. I'd suggest to use at least
"-O2" - otherwise, it will run disappointingly slow.

Warning: Extension: Tab character in format at (1)
You can ignore this warning. (For some reasons, tabs for indenting give
only a warning with -std=f95/f2003/f2003 and -Wtab while tabs in a
format string give an error with -std=f* and otherwise unconditionally a
warning.)

Try: file='y.his' instead of "name=".
