Careful. The -fdefault-integer-8 is just a tip of a difference iceberg.
Omit this option, and replace c_int by c_long. You'll then get:
bind_c_usage_10.f03:45:32:
45 | integer(c_long) function func1() bind(c, name="myFunc1")
| 1
Error: FUNCTION result func1 cannot be of type INTEGER(8) in FUNCTION func1 at
(1)
This is a resolution bug in gfortran, and there is IIRC sort of a duplicate.
