Re: [Patch fortran] PR32957 - C/Fortran interoperability and -fdefault-integer-8

Thanks for the quick review, committed as r257985. I have spotted a few similar issues in my recent testing and I have problem with gfortran.dg/bind_c_usage_10.f03 when using -fdefault-integer-8:

/opt/gcc/_clean/gcc/testsuite/gfortran.dg/bind_c_usage_10.f03:66:31:

   integer(c_int) function func4()
                               1
Error: FUNCTION result func4 can't be of type INTEGER(4) in FUNCTION func4 at (1)
/opt/gcc/_clean/gcc/testsuite/gfortran.dg/bind_c_usage_10.f03:59:31:

   integer(c_int) function func3() bind(c, name="myFunc3")
                               1
Error: FUNCTION result func3 can't be of type INTEGER(4) in FUNCTION func3 at (1)
/opt/gcc/_clean/gcc/testsuite/gfortran.dg/bind_c_usage_10.f03:52:31:

   integer(c_int) function func2()
                               1
Error: FUNCTION result func2 can't be of type INTEGER(4) in FUNCTION func2 at (1)
/opt/gcc/_clean/gcc/testsuite/gfortran.dg/bind_c_usage_10.f03:45:31:

   integer(c_int) function func1() bind(c, name="myFunc1")
                               1
Error: FUNCTION result func1 can't be of type INTEGER(4) in FUNCTION func1 at (1)

AFAIU the code func* are integer(c_int), then why these errors?

TIA
